While the tinkerer in me would love to, the pragmatic side of me cannot ignore the speed boost, specially for prototyping programs.

If I write everything by hand, I know I'm leaving velocity or quality on the table. If I use LLMs, I can eventually get good output from it, either by going faster with moderate quality, or by going slower and focusing on better code. But that makes me hate the whole development process. I enjoyed modeling a problem with types and, writing functions that work on these types. Automating this process (either the cognitive work to come up with them, or the typing work to bring them to life) takes away most of my fun.
