I would love to learn more what can be done! (And especially for projects in Southern Germany where I am based).

Apparently, a huge part of the opportunities are in embedded computing. One observation I have that there is an AI hype now, but very few people in that area realize how much can be achieved with "conventional" methods like classical signal processing strategies, for example predictive filtering. A huge part of embedded computing is just concerned with getting a board running, at which point you are not farther than when you have powered on a PC and finished to log in.
