The answer to their question (to paraphrase: "why are opinions so polarised on Go?") isn't a technical one. It literally is just people arguing personal preference.

If he or she wants a technical arguments for why they should or shouldn't use Go (which is a subtly different question but results in a significantly different answer) then there is already a wealth of debate on that topic already so there's no new technical perspectives that I - nor anybody else - could actually add.
