I use various agentic dev tools all day long, mostly with Opus. The tools are very capable now, but when planning mid-complexity features, I find the time estimates hilarious.

Phase 1: 1-2 weeks

Phase 2: 1 week

Phase 3: 2 weeks

8 to 12 hours later, all the work is done and tested.

The funny part to me was that if I had an AI true believer boss, I would report those time estimates directly, and have a lot of time to do other stuff.

Human time estimates are bad, but the ones that AI gives are just absurd. I've seen them used from small things like planning interviews and short presentations, all the way up to large scale projects. In no case do they make any sense to me. But I think people end up trusting them because they look so confident and well planned due to how the AIs break things down.

When youre the boss telling kids how to work what time esti.ates will you believe?

Tis the cycle
