I mostly agree with that. Probably because I consider myself a good programmer and am perfectly fine to delegate all sysadmin stuff.

I think the point is they are distinctly different skillsets. Programming is very different from setting up and maintaining systems. There's a tiny bit of crossover, but not all that much.

Sysadmins do need a basic sense for coding, however they tend use different technologies than the one people generally use to write web applications (though maybe they'll release Bash on Rails sometime soon)
