While I don't think this is novel I am a believer that AI has changed computing forever in the same way the tweet implies.

There is absolutely no way I could have done all of this without AI. I don't really consider most of it too be slop, ive been an engineer for 20 years. I care a lot about the details and the underlying properties of the system. I had shipped my side projects years before AI that had real users so I have a good idea of what it takes to ship something end to end that people can actually use. It's mostly about the details and ease of use and the last 20% is the hardest. Some of us know that from our day jobs but it is different when you have to it all yourself and be responsible for every choice.
Yeah the ability to build bespoke apps in a reasonable amount of time is awesome. Cool stuff!
