It's not the "Gods of IT" you should be looking to. Those people are concerned about, as you said, getting stuff done in high-level languages cheaply and quickly.
The kind of thing you're looking for is still alive and well... in Linux. That's where the hackers are, the people who care about how the machine works at all levels.
I just spent all of 30 seconds finding, downloading, and using Bywater BASIC to print out "foo" in a loop (10 print "foo", 20 goto 10 natch).
You're looking at the wrong platform to provide that kind of experience. Granted, that's partly your point, but it's not our fault we have a better platform to play on now. Linux is the hobbyist OS of today, like those wonderful Apples, Commodores, and Ataris of old.
