I’ve had to move away from thinking to meta-thinking. Most of my engineering effort is now focused on figuring out what information and process to feed a model, and then observing how it runs and tweaking the results until it’s not crap. You also stop worrying about the time it takes to code things and start worrying about tampering down on tech debt aggressively. Things that you would have never had time for before (refactoring to make the system slightly better) become incredibly possible and easy now.
