(1) That's where the "get a qualification or training" suggestion kicks in.

(2) You just named another point why toying around with 7400s may not be 
wasted time after all: FPGAs are essentially nothing but a bunch of 
(N)AND and (N)OR gates, plus a few flip-flops, that you can "wire up" 
programmatically. Once you have toyed around with 7400s and the like, 
going for FGPAs is a piece of cake. All you need is a dev tool (some 
FPGA manufacturers give you at least some trial version for free) and a 
dev kit (which you can solder together yourself in some cases; that's 
what I did), and there you go.

At present, maybe. If you keep going (and possibly do some qualification 
on it), things could look different soon.
