Yes, exactly. Though, I have to say, going from software to hardware was quite magical: You can suddenly affect the physical world, which is amazing. Plus, if you already know software, adding hardware to the mix rounds you out very well, and opens up a large array of things you can make.

I very strongly recommend designing a few things in OnShape or FreeCAD or SoveSpace and getting a 3D printer once you get the hang of that (it shouldn't take you very long at all, maybe a few evenings).
Machined parts I find pretty hard, but then again I also found plastic things impossible before getting a printer and they turned out to be quite easy.
