Pietro Schirano, a designer and early adopter of AI, illustrates an industry evolution from "human prompting AI" to "AI prompting humans" over six months. In 2023, he used detailed prompts; by 2026, he reached the stage where AI actively asks "What do you need me to help you with?" This trajectory of "frontier users" contrasts with ordinary users still in the "detailed prompts" stage in 2026 and developers in the "AI autonomous planning" stage. The capital impact shows the market size for "prompt engineering" was $500 million in 2023, expected to drop to $100 million by 2026, while the market for "AI autonomous agents" is projected at $15 billion in 2026, rising to $50 billion by 2027. Funding shifts from "prompt optimization" to "AI subscriptions" with monthly fees of $20-500. Analogous cases include "search engine optimization," whose market dropped from $5 billion in 2010 to $1 billion after Google's 2020 algorithm upgrade, and "App interface design," expected to fall from $20 billion in 2020 to $5 billion after AI-generated UI in 2026. Human-computer interaction is in the "prompt extinction phase": in 2023, prompts were necessary for 90% of users; by 2026, prompts are optional for 50% of users; by 203
