Clearly you should change jobs to a place with more devs, hopefully you will find some peers there.
Don't be frustrated with slower people. Part of it is the cannibalization effect. If a team has a dominant striker, some of the others will be scoring fewer goals than their potential. You might actually be doing them a favor by moving on. The other thing to remember is that great players still need water carriers, or they'll be wasting their time carrying water themselves. Lastly, if you don't have some 1X people around you, nobody will know you're a 10X. So be happy that you are so good and so influential.
