It is hard to know what works well, as everyone is different. I would look at things that seems fun. Fixing stuff, from bikes to engines? Physical therapy? Teaching kids? And so on.

For some you may be even able to leverage your software skills.

Here is an idea of something that will be the last to be replaced by AI: Public Speaking.

If you have time, start developing your public speaking skills. This will give you the edge over other engineers within your company, especially if you know how to use it. Additionally, you'd be able to survive if you are layed off by either moving to an adjacent field (pre-sales, sales, CTO...etc) or just start attending and presenting at conferences. Hope this helps

You mean "avatar-free 3D speaking" where you are confirmed to be real by your presence in a room?
