Added context, etc.

Mar 17, 2011 at 8:22 comment added user1041 Being electrical engineer I didn't have much problem with the simultaneity, it was quite a liberation in fact. As for the pain of implementation, well the uP is a niche-solution to specific classes of problems that transform the problem to solution that can be described as algorithms, a concept originally taken from mathematics. A problem with inherent parallelism is among the problems easy solvable and VHDL and FPGA's come in handy at that times.
Jan 10, 2011 at 20:14 comment added timday I did a little VHDL once. I had a real epiphany moment when I suddenly realized that, as I was adding code, effectively more and more hardware would appear to implement that code and it was all running simultaneously. Like multithreaded programming with truly unlimited simultaneously executing threads; maybe people with access to unlimited nodes on EC2 or map-reduce clusters get a similar buzz. (But shortly afterwards I came to appreciate what a complete pain it is to implement anything non-trivial in these langauges, and ran away).
