Lisp makes it really easy to build infrastructure and multiplier-level (Level 2) contributions that affect the whole shop. When you have 1.3-1.4 programmers (scale here: http://michaelochurch.wordpress.com/2012/01/26/the-trajector... ) who aren't ready to take on projects that will affect other people in such a major way, you can get bad results. That's a management problem, though. Inexperienced developers need to have opportunities to experiment, but if others are forced to sit downwind of their work, then management is behaving badly.
