I don't feel this way. I have just been tackling more and larger problems, I think? This week one of many things for example is switching a multi-master KV store for tracking views on individual objects to tiered hyperloglogs that periodically merge. I could do this without AI, but it would take me a week instead of a day.

I think, if you're not feeling challenged, you're probably just doing the same work but faster. You should try to tackle harder problems, too!
