By lines of code, almost by an order of magnitude.
Some of the code is janky garbage, but that’s what most code it. There’s no use pearl clutching.
Human engineering time is better spent at figuring out which problems to solve than typing code token by token.
Identifying what to work on, and why, is a great research skill to have and I’m glad we are getting to realistic technology to make that a baseline skill.
Well, you will somehow have to turn that 'janky garbage' into quality code, who will do that then?
