Tier B · TL;DR
AI's 80% ceiling is the startup opportunity: complete the last mile to 100%.

Claim

The number of things that AI can do well till the 80% mark and then leave you out to dry = the number of startup ideas that can be built to help complete the workflow and take it as close to 100% as possible. And that number is HIGH!!

Mechanism

AI excels at the bulk of a task but fails at the final, nuanced completion. Startups that build the finishing layer—bridging the gap from 80% to 100%—capture massive value by delivering full, reliable outcomes.
