This framework evaluates skills based on their long-term value and earning potential, focusing on three essential criteria: entry barrier, AI defensibility, and profitability. Each skill is ranked from S-Tier (most valuable) to F-Tier (least valuable) for clear career decision-making.
Skills with low barriers like social media management can be learned in a weekend, while high-barrier skills like public speaking, trades, and sales require extensive practice, certification, or psychological resilience. Video editing and project management fall in the middle—editing demands design sense, while project management is increasingly aided by AI.
AI replacement likelihood is critical for long-term viability. Social media management and email management are highly susceptible to AI disruption, as automated tools already handle most tasks. Public speaking remains exceptionally defensible, as machines cannot replicate the emotion and human connection required. Trades are defensible for now, though gradual automation looms. Sales maintains some defensibility through human nuance in closing deals, but AI is encroaching. Project management faces high vulnerability, with AI automating substantial aspects.
Premium skills command high earnings. Public speaking is among the most profitable, with top earners commanding up to a million dollars per speech. Sales is likewise lucrative because selling drives all business. Trades offer solid but capped earnings due to geographic constraints. Social media management, email, and video editing are becoming commoditized as AI handles more tasks, resulting in lower or uncertain income.
Skills scoring highly in all three criteria—difficult to master, resistant to AI automation, and highly profitable—earn S- or A-tier designations. Public speaking is A-tier: hard to learn, can't be replicated by AI, and pays exceptionally well. Its substantial learning curve prevents it from reaching S-tier.
B- and C-tier skills stand out in one or two criteria but fall short in the third. Social media management is easy to learn but vulnerable to AI with dropping profitability, ranking around B-tier. Trades are hard to learn and defensible but have capped profitability, placing them in C-tier. Sales is lucrative but increasingly less defensible as AI progresses.
Skills that are easily replaced by AI and no longer command premium pricing fall into D- or F-tier. Email management is now handled mostly by AI tools, becoming an administrative afterthought rated D-tier. Video editing is losing defensibility and profitability as platforms adopt AI-driven editing. Such skills are poor investments for career growth and stability.
This analysis evaluates a wide range of professional and technical skills for their resilience, profitability, and defensibility in the artificial intelligence era.
Public speaking is rated A-tier due to its high barrier to entry, strong defensibility from AI, and significant earning potential. Elite speakers earn up to a million dollars for a single talk, and humans need to feel the human connection that AI cannot replicate.
Sales is viewed as the ultimate meta skill, applicable across business contexts. While AI handles outbound calls and basic objections, the final close requires human nuance and relationship-building. Young sellers can out-earn their parents, making sales A-tier, though it's trending toward disruption as AI advances.
Cybersecurity earns B-tier ranking for its challenging learning curve and constant adaptation to complex technological threats. As cyberattacks become more sophisticated through AI, demand for skilled defenders will grow, and salaries remain strong.
Software development is now highly approachable as AI streamlines coding. However, defensibility is fading as AI increasingly generates code. Pay remains attractive but declining, securing a B-tier rank behind cybersecurity.
AI automation still commands healthy fees as companies seek expert guidance, but defensibility is rapidly weakening as AI agents automate the automations and employees learn to build their own systems. The field sits at B-tier with uncertain long-term prospects.
Lead generation is challenging, requiring genuine understanding of market psychology. While AI can assist, practitioners who master adaptation will stay relevant, making it mid-B to low-A tier.
Answer Engine Optimization (AEO) is the evolution of traditional SEO for the AI age, aiming to place products as direct answers in AI chats. It's profitable for now but has uncertain defensibility as AI models improve.
Trades such as plumbing and electrical work remain defensible against automation, as robots aren't yet repairing pipes or wiring homes. These roles are in demand but scalability is limited because time is directly exchanged for money, placing trades at C-tier.
Project management is increasingly commoditized as AI systems take over scope, budget, and timeline management. The barrier to entry is low, defensibility is weak, and profitability is declining, making it D-tier.
Prompt engineering is heading for obsolescence as AI systems now generate and optimize their own prompts. It's easy to learn, justifying a C-tier rating but with poor long-term prospects.
Media buying is rapidly automated by AI platforms that manage creative content, ad spend, and optimization. Major layoffs reflect shrinking demand, putting media buying at low C-tier.
Social media management still commands demand for regular posts and engagement, but AI can automate much of the work. Budgets are shifting to AI tools, leading to declining profitability at the low end of B-tier.
Graphic design is severely disrupted by AI tools that instantly create websites and campaigns. While taste matters, most jobs are moving to automated platforms, relegating graphic design to D-tier.
Email marketing was once lucrative, but now most campaigns are optimized by AI using historical data. The job is easy to learn, almost administrative, and pays far less, ranking it D-tier.
Copywriting is in decline as businesses accept "good enough" AI-generated content. Only rare, elite copywriters delivering high-conversion results can still earn top rates, placing the profession in the upper range of D-tier.
Traditional SEO is becoming obsolete as AI chatbots and answer engines circumvent the need for ranked search results. Defensibility is minimal and the job increasingly unprofitable, sinking SEO to F-tier.
Day trading remains popular but is extremely difficult to profit from consistently and highly vulnerable to AI-powered trading bots. Few succeed and most lose money, leaving day trading at F-tier.
The emergence of artificial intelligence is rapidly shifting the landscape of careers, automating many tasks previously handled by humans.
Data analysis, once a high-value consulting role, now faces a significant existential threat from AI. Tools can efficiently handle organizing, cleaning, and deciphering data, making the barrier to entry extremely low. The long-term defensibility of routine data analysis as a career skill is minimal, with value and compensation dropping.
Roles demanding nuanced judgment and emotional intelligence—such as sales and public speaking—remain less vulnerable, as AI cannot truly replicate the authenticity and trust that humans foster in high-stakes, relationship-driven environments.
Creative professionals face a complicated reality. While AI generates outputs quickly and at scale, the ability to use these tools strategically—blending human creativity with AI's speed—ensures that those possessing true creative mastery remain valuable.
Practitioners who focus on high-value functions such as strategy, creative thought, and human judgment will sustain or grow their income, with AI responsible for routine tasks. Success depends on embracing AI as a tool and using it to magnify existing skills, rather than attempting to compete with automation. Workers who fail to adapt risk displacement.
Media professionals who move beyond tactical content execution into strategic roles are positioned to thrive, while those relying on routine production face obsolescence. Copywriters who pair AI with psychological insight will continue to generate value, while those with only basic skills are easily replaced.
Dan Martell outlines an approach for selecting and mastering skills that are resilient and highly valuable in the rapidly advancing world shaped by AI.
Success depends on learning skills that are defensible, profitable, and open doors across industries. Sales and public speaking are foundational meta-skills prized in every sector. Cybersecurity and software development stand out for their high barriers to entry and strong profit potential. Martell emphasizes that personal aptitude and interest are more important than choosing the theoretically perfect skill—what's critical is choosing something enjoyable, which increases the likelihood of deep mastery.
Martell advocates leveraging AI as a force multiplier for faster skill acquisition. He urges learners to proactively use AI for tailored instruction and guidance, asking AI directly for incremental learning steps and practice exercises. Martell encourages experimenting with AI to assess aptitude for various high-value skills before fully committing.
Martell's core philosophy is to always disrupt himself before being disrupted by AI. This means continually monitoring which skills are losing market relevance and transitioning to new abilities before obsolescence occurs. He suggests publicly sharing documented learning journeys, which builds personal brand and authority. Ultimately, the goal is to leverage AI as an accelerator and enabler, ensuring one is always ahead of industry shifts and automation trends.
1-Page Summary
This framework evaluates skills based on their long-term value and earning potential, focusing on three essential criteria: entry barrier, AI defensibility, and profitability. Each skill is ranked from S-Tier (most valuable) to F-Tier (least valuable) for clear career decision-making.
Skills with low barriers of entry, such as social media management, are easy to learn, often requiring only a short time or guidance from online content. For instance, one can pick up social media management in a weekend. Conversely, skills like public speaking and trades (plumbers, electricians) involve high entry barriers. Public speaking is hard to master and demands significant practice; trades not only require extensive learning but also certification and hands-on experience. Sales, while technically easy to learn, is psychologically demanding—the best salespeople overcome significant rejection with resilience, making mastery genuinely challenging. Video editing and project management fall somewhere in the middle: video editing requires a distinct sense of design and taste, making it hard to excel at, while project management is valuable but relatively easier to learn, though increasingly aided by AI.
The likelihood of AI replacing a skill is a critical measure of long-term viability. Social media management is highly susceptible to AI disruption—automated tools can already write posts, captions, and manage content calendars, with future models promising autonomous performance. Email management is similarly at risk, as most emails are written or assisted by AI, reducing defensibility. Video editing is increasingly handled by AI, making it less defensible over time. Public speaking, however, is exceptionally defensible against AI: machines simply cannot replicate the emotion, nuance, and human connection necessary for powerful presentations. Trades like plumbing and electrical work are defensible for now; AI and robots are not close to physically replacing humans in these roles, though gradual automation is possible. In sales, AI is encroaching on outbound calls and objection handling, and while AI assists the sales process, closing deals still requires irreplaceable human nuance—though this defensibility is trending downward. Project management is predicted to be highly vulnerable to AI in the near future, with many tools and agents already automating substantial aspects of the work.
Premium skills command high earnings. Public speaking is among the most profitable, with top earners commanding up to a million dollars per speech. Sales is likewise lucrative—talented closers can earn exceptional incomes, even as young adults, because selling drives all business. Trades offer solid earnings because of persistent demand, but remain capped since individuals often sell their time directly and face geographical constraints. Social media management and email, meanwhile, are commoditized; as AI handles more of these tasks, businesses pay less. Video editing, too, is shifting toward performance-based compensation, often resulting in lower or uncertain income. Project management has modest profitability, as businesses spend more on change implementation through AI than traditional project oversight.
Skills that score highly in all three criteria—difficult to master, resistant to AI automation, and highly profitable—earn S- or A-tier designations. Public speaking, for example, is A-tier: it’s hard to learn, can’t be replicated by AI, and pays exceptionally well. Its only limitation is the s ...
Skills Assessment Framework: Entry Barriers, Ai Defense, Profitability
This analysis evaluates a wide range of professional and technical skills for their resilience, profitability, and defensibility in the artificial intelligence era. Ratings from A-tier to F-tier reflect their susceptibility to automation and evolving market demands.
Public speaking is rated A-tier due to its high barrier to entry, strong defensibility from AI, and significant earning potential. Successful public speakers inspire audiences in ways that AI cannot replicate—"Humans need to feel the human." The profession commands the highest fees, with elite speakers earning up to a million dollars for a single talk, making it extremely profitable and safe from automation.
Sales is viewed as the ultimate meta skill, applicable to business, recruiting, negotiation, and even family dynamics. It is challenging because it requires overcoming rejection and psychological hurdles, not just mastering basics. While AI is already handling outbound calls and basic objections, the final close often needs human nuance and relationship-building—roles AI is beginning to encroach on but hasn't fully supplanted. Sales positions can be extremely lucrative; young sellers can out-earn their parents, so the skill remains A-tier, just behind public speaking. However, it is trending toward disruption as AI advances.
Cybersecurity earns a B-tier ranking. The skill is challenging to learn, involving constant adaptation to complex technological threats. As cyberattacks become more sophisticated through AI, demand for skilled defenders will only grow. It remains highly defensible, and salaries are strong, sometimes allowing top professionals to "write their own check." However, its difficulty places it lower than A-tier skills.
Software development is now highly approachable, as AI streamlines coding and app development. Even young teens can build functional sites or games with minimal prior exposure. However, defensibility is fading, with AI increasingly able to generate code and automate tasks; future demand will focus more on product thinking than raw coding. Pay remains attractive, but rates are declining as automation increases, securing software development a B-tier rank just behind cybersecurity.
AI automation, or the orchestration of business workflows using AI, still commands healthy fees as companies seek expert guidance to automate operations. However, defensibility is rapidly weakening as AI agents automate the automations, and as ordinary employees learn to build and deploy their own systems. The field is shifting quickly, and while profitability is high now, the long-term outlook is uncertain. AI automation sits at B-tier due to shrinking defensibility, with future prospects tied to the rise of AI agents.
Lead generation is challenging, requiring genuine understanding of market psychology to attract quality leads. AI can assist, but practitioners who master adaptation will stay relevant. While the field is profitable (businesses pay for leads), it's less lucrative than sales proper, yet still valuable and relatively defensible, making it a mid-B to low-A tier skill.
Answer Engine Optimization (AEO) is the evolution of traditional search engine optimization for the AI age, aiming to place products or services as direct answers in AI chats and search. It's a tough and rapidly changing skill, profitable as long as companies want prime placement in search answers. However, defensibility is uncertain: As AI models improve, their resistance to external optimization may reduce the value of AEO expertise.
Trades such as plumbing and electrical work remain defensible against automation, as robots are not yet repairing pipes or wiring homes. These roles are in demand and profitable on a per-job basis, but scalability is limited because time is directly exchanged for money. Unless trade skills are parlayed into a business, earnings will be capped. This places trades at C-tier—valuable and defensible, but limited by personal labor.
Project management is increasingly commoditized, as AI systems take over scope, budget, and timeline management. There remains some value in change management, but the barrier to entry is low, defensibility is weak, and profitability is declining as more tasks are automated and fewer project managers are needed.
Prompt engineering, once crucial, is now heading for obsolescence. AI systems now generate and optimize their own prompts, making specialist knowledge less valuable. It's easy to learn and still related to the AI space, justifying a C-tier rating but with poor long-term prospects.
Media buying, the process of purchasing and managing advertising, is rapidly automated by AI platforms. Platforms now manage creative content, ad spend, and optimization. Major layoffs in the field reflect shrinking demand, and while complexity in multi-platform campaigns provides some residual value, profitability and defensibility continue to drop, putting media buying at the low C-tier.
Analysis of 20+ Skills and Their Viability in the Ai Era
The emergence of artificial intelligence is rapidly shifting the landscape of careers, automating many tasks previously handled by humans and forcing workers to rethink how to create value.
Data analysis, once considered a high-value consulting role due to its ability to uncover insights for decision-makers, now faces a significant existential threat from AI. The process of organizing, cleaning, and deciphering data—which was previously the domain of trained analysts and consultants—can be efficiently handled by powerful AI models. Tools like Claude have launched a comprehensive suite of features to manage financials, data cleanup, and data visualization, and can even generate manipulation-ready artifacts. In practice, many teams already use AI for these tasks, making the barrier to entry extremely low. Experience or a quantitative background no longer provide meaningful differentiation, and the long-term defensibility of routine data analysis as a career skill is minimal, with value and compensation dropping accordingly.
While routine technical skills are increasingly automated, roles that demand nuanced judgment and emotional intelligence—such as sales and public speaking—remain less vulnerable. AI still cannot truly replicate the authenticity and trust that humans can foster in high-stakes, relationship-driven environments.
Creative professionals face a complicated reality. While AI generates outputs quickly and at scale, the ability to use these tools strategically—blending human creativity with AI's speed and depth—ensures that those possessing true creative mastery remain valuable in the marketplace.
Rather than eliminating all opportunity, AI shifts the baseline. Practitioners who focus on high-value functions such as leveraging strategy, applying creative thought, and utilizing human judgment will sustain or grow their income. AI becomes responsible for routine tasks, freeing these professionals to focus on areas where human strengths matter most.
Success now depends on embracing AI as a tool and using it to magnify existing skills, rather than attempting to compete ...
