What happens when two users book the same seat with AI code?

Race condition city: both see it free, both lock it. Fix with atomic DB ops like UPSERT or SELECT FOR UPDATE.

Can Claude handle production database design?

It nails basics fast, but misses long-term bloat and expiry cleanup. Add your own TTLs and sweeps.

Nah — it speeds boilerplate. Judgment on concurrency and systems? That's still human territory.

Two users hit 'book' on the same seat. Claude's API let both win. That's when my AI intern's enthusiasm turned into a liability.

AI tools like Claude excel at fast boilerplate but routinely miss critical concurrency bugs like race conditions. 𝕏
Reviewing AI output is now a core dev skill — think 'drunk intern' that needs oversight. 𝕏
Future AI will need failure simulation to gain real production intuition. 𝕏
