That's fair, I have plenty of international coworkers and I think (and from what I hear from them), that Belgium is decently welcoming, at least in large cities.

I do take the train quite often as I said, anything on large axes is usually fine (Brussels - Charleroi, Brussels - Antwerp, etc) but yeah smaller lines are usually struggling some more.

I wish we had more ambitious governments in general, not only in terms of energy but also in the (bio)tech scene, which used to be touted as our great strength (we do have a lot of pharma companies though).

Agreed.

Running ancient nuclear power plants in one of the most densely populated countries does not seem wise.

These plants have been running with phase-out in mind for the last 20 years.
