My approach to this is to have a personal venv based on a modern Python3 
and put its bin near the front of my $PATH. The pip and python come from 
it. But I tend to type "pip3" anyway - still the pip from my venv.

Don't change the system default Python - many system scripts rely on 
that and may break. If an OS update changes it, it should also update 
all the dependent scripts and so be ok, but an ad hoc change of only 
part of the system is asking for trouble.
