Probably, but also probably not on the same level. This doesn't seem like a very useful objection, both because it's obvious and because it's very weak.

Probably true. But it would take us longer, code base would be larger and still harder to maintain and more error prone compared to Go.

It's a very old project and super important core technology - we did refactors before and I was somewhat scepitcal when lead devs on the project suggested to use Go instead for the next "refactor". I was blown away by the quality, speed and productivity.

If you're building server infrastructure that needs to be performant, consider Go.

This statement is only true if refactoring is not allowed.
