So, at least we've got from 'I'm too gifted to learn from anyone' to 'I'm in a difficult position without access to peers to learn from', which sounds more plausible and is probably worth sticking with.

I guess you have two options really - find another job that will give you access to a team, or start doing something to give you contact with programmers outside of work, whether that's getting involved with an open source project, finding a meet-up to go to, taking a class, etc. In any case, approaching it with an appropriate level of humility is probably a good idea.
