Would I use these skills professionally, to make money ? Not likely, but who can rule out the possibility.
No. That is, there's always a small chance and there are exceptions to the rule, but in general, no, you will not suddenly gain any skills on an Amiga nowadays which are likely to make you any serious money in the future. Selling selfmade hardware projects to other geeks might be your only chance...
Hmm...almost I think I have answered my question-if I want to do these things, any platform will require the correct software/hardware combo. Do I like (the Amiga) (any) platform enough to invest time and money into what would essentially be a hobby ?
And that's entirely up to you!
