I've built easily a dozen personal apps in the last few months that I have no plans on releasing or sharing, run locally, and solve very specific productivity (or one-off) issues for me.

I would never have spent the time building these apps in the pre-LLM days because the effort wouldn't have been worth the gains.

But now? Sure Claude, build me a MacOS app in Swift that does this exact thing I need. Less than an hour later, it's done.
