Remember when you had to hand label a thousand images for a simple model?

Back in 2018, I spent a whole week labeling street sign photos for a college project. Did about 50 an hour, my eyes were crossing. Then last month, I used an auto-labeling tool on a similar dataset. Finished the same work in under two hours. The accuracy was maybe 95% right out of the gate. It's wild how that grind just vanished. Anyone else have a 'before and after' moment with a specific AI tool?

That auto-labeling speed sounds nice, but that 5% error rate is a real problem. You still have to check every single label, and hunting for those wrong ones can take longer than just doing it yourself from scratch sometimes. Last project I did, the AI kept mixing up similar looking parts, and fixing its mistakes added hours. The grind didn't vanish, it just changed into a different kind of tedious work.

Yeah I used to think auto-labeling was the answer to everything... but then I had a project where it kept marking every round object as a stop sign. Spent more time fixing those than if I'd just started from zero. It really depends on the data.
