For me, the friction that gets added when you're doing Lisp and nobody else is cannot be emphasized enough. If your job is to accomplish something useful for somebody else, and you have to coordinate with other humans, directly or indirectly, you are setting yourself an uphill journey using tools that others don't understand.

Cutting yourself off from 'society' is a super duper duper aggressive play that works out badly almost all of the time. It has its place but you better be damn sure that you know what place that is.
