By switching this early to Go you'd have to write much of what is available as third party libraries in Python yourself.
This would hopefully lead on to job opportunities down the road.
I managed to get in fairly early on Drupal, and it's been a nice source of work over the years.
Projects like this might help, but I suspect there will always be someone willing to port a library to be native.
For example, there's SWIG: http://www.swig.org/
Unfortunately, there tend to be subtle issues of impedance mismatch that make cross-languages bindings never feel quite right.
