Actually, very few of the bright ones want to live downtown. Most coders in downtown Denver are average at best. The goods ones will be in Boulder, ft. Fun, etc.
For example, you will find Windows coders, Oracle DBAs, etc downtown.
U find the intelligent coders in Boulder and ft. Fun running *nix, coding in C/C++, python, java, swift, rust, and MySQL, nosql,postgres DBs.


And I seriously doubt that Amazon wants a bunch of average to has-beens.
