AI models will quickly automate the majority of expert work, but they will struggle with the final, most complex 25%. For a long time, human expertise will be essential for this 'last mile,' making it the ultimate bottleneck and source of economic value.

AI agents are rapidly transforming software development and knowledge work, but their impact on professions requiring physical robotics, like surgery or auto repair, is on a much longer timeline. The AI revolution is arriving in phases, with the digital world being upended first and the physical world to follow later.

Kalanick posits that as AI automates most tasks, the remaining human-centric jobs (e.g., plumbing) will become the primary bottleneck for progress. This scarcity will make these roles the "long pole in the tent," dramatically increasing their economic value and earning potential until AGI arrives.

Brendan Foodie predicts that as AI automates digital roles, the displaced workforce will shift to physical world jobs (from robotics data creation to therapy). He argues this is because physical automation progresses much slower than digital automation, which benefits from rapid, self-reinforcing feedback loops.

The key to predicting AI's economic impact is not focusing on the abundance it creates, but identifying what will remain scarce. As automation made goods cheap, the economy shifted to scarce services. The next economic transformation will similarly be driven by whatever human skills or experiences AI cannot replicate.

A powerful mental model for the future of work is a three-step pipeline. If a job can be done remotely in a high-cost country, it can be offshored to a low-cost one. Once offshored and process-driven, it becomes a prime target for AI automation. This positions remote work as a transitional phase, not an endpoint.

The fundamental economic shift is not just job automation but an inversion of roles. AI, as pure intelligence, will become the employer, hiring humans as contractors for physical tasks it cannot perform, like visiting a warehouse or collecting brochures. Intelligence becomes a cloud commodity, while physical presence becomes the service.

While digital AI optimizes ads and creates content, physical AI will transform the core of the global economy—manufacturing, mining, logistics, and transportation. The companies impacting the physical world are poised to be larger than their digital counterparts in this intelligence revolution.

The Industrial Revolution shifted economic power from land to labor. AI is poised for an equally massive transition, making capital, not labor, the primary driver and limiting factor of production. As AI increasingly substitutes for human labor, access to capital for machines and computation will determine economic output.
