Take a SQL schema, and ask AI to generate crud endpoints for the schema, then sit down and code it by yourself. Then try generating client side actions and state management for those endpoints. Time yourself, and compare how long it takes you. Even if you're fast and you cut and paste from template work and quickly hand edit, the AI will be done and on a smoke break before you're even a quarter of the way through.
Ask the AI to generate correctly typed seed data for your database, using realistic values. Again, the AI will be done long before you.
Try porting a library of helper functions from one language to another. This is another task where AI will win handily
Also, ask AI to write unit tests with mocks for your existing code. It's not amazing at integration tests but with mocks in play it slays.
I appreciate it.
It is true it is faster than humans at some tasks, but the remaining tasks were most of the time, you can't gain more than 11% speedup by speeding up 10% of the work.
Things don't move forward by saying it can't be done or belittle others accomplishments.
