Sure. If you've done nothing significant with the language then a breakup is easy. Easy come, easy go.
If you've spent years, or even decades, building a portfolio with Python then the breakup is going to be much harder, just like in human relationships. Some things will make sense to leave in Python until end-of-life. Other things will be worthwhile to migrate to Go. Of course your new greenfield projects can start off using Go.
Just know this - you're going to go through this again in another 10-15 years, if not sooner. I've been writing software now for 40 years, that's just the way it goes.
