Because we love tech? I'm absolutely terrified about the future of employment in this field, but I wouldn't give up this insane leap of science fiction technology for anything.
A really good pattern-matching engine is an "insane leap of science fiction"? It saves me a bit of typing here and there with some good pattern matching. Trying to get it to do anything more than a few lines gives me gibberish, or an infinite loop of "Oh, you're right, I need to do X, not Y", over and over - and that's Opus 4.5 or whatever the recent one is.
Would you give it access to your bank account, your 401k, trust it to sell your house, etc? I sure wouldn't.

The brain rot from the author couldn't even think of "unit test".
I love tech - tech that actually works well. The current tech we have for AI does not, so I'm not excited about it.
