5) Even in CPython, I/O-bound processes are not slowed significantly

Its ONLY when you have two or more CPU bound threads that you may have
issues.
And when you have a CPU bound

So I'm in a startup where we are considering using python as our primary
development language for all the wonderful reasons you would expect.
However, I've had a couple of things come up from mentors and other
developers that is causing me to rethink whether python is the right
choice. I

Is the limiting factor CPU?
If it isn't (i.e. you're blocking on IO to/from a web service) then the
GIL won't get in your way.
If it is, then run as many parallel *processes* as you have cores/CPUs
