I mean… will any employer possibly care if I told them that I've worked through half of SICP, internalized maybe thirty Emacs commands, can do some moderately interesting stuff with sed and pipes on Unix, and can write crappy Perl code? Will all of this stuff remain merely a secret weapon of mine while I continue on in work environments where such tools are unknown, actively feared, or completely off the radar? Now what? Start your own company (duh, right?), or become a manager at one. If you know these things, you can probably spot talent a lot better than the average manager... and companies want managers who can spot talent well.
