Don't get me wrong, I also do work in the financial aspects of it and that'... Well, useless is too strong a word, but in the grand scheme of things it's frankly useless. There is so much ridiculous leglislation that can be digitized, some of it is stupid. Like how you can get various tax benefits if you split what you and I think of as a single solar farm into 100 smaller companies. How to game the various financial tariffs, how to figure out the optimal direction for solar cells based on market data. That sort of stuff. Then there is the reasonable parts, like how Italy has an agency which requires all money transactions to go through them as an anti-mafia thing (sorry I can't be more clear on that part I didn't make it). Over all though, it's fun to work with stuff that has a real world use.
