I don't know who would pay for data sciencing at the level that you probably want outside finance except possibly some of the AI outfits in a hurry, maybe even relatively new ones but flush with cash...
Actually this is the point. I'm not that after money anymore. Would love to learn something new again. So would be happy to get far far less, but learn for example robotics. Really excited about it.
For sure if money would be the only metric, I should try to stick to trading. Even if my stuff doesn't work, I could try to join some prop trading shop. Could imagine doing so to be honest, but right now just want to try something new.
Well, I think there is lots of interesing DS stuff to be done. I've had very good value out of a couple of DS folks who worked for me. And on the side while doing my PhD I'm trying to absorb some DS skills because they will be useful, and intresting on the way!
Consider doing a DS-flavoured degree, eg at Master's level, part-time? Maybe do something more mundane part time to pay for it?
