There is a pretty interesting rabbithole of semiconductor industry blogs (seminanalysis, chips and cheese, fundamental bottom) that can be fairly interesting to stay up to date on current hardware developments even without an CE/EE background.

In EEng most positions in Germany are without mandatory teaching. Unless you want to, as you would need teaching experience to be eligible for a professorship.

Germany is actually really good if you have a full-time position, as the salary is somewhat comparable to a normal job, at least in CS/CE.
