Since then we've gotten pretty serious - we play at a local club, went to a tournament, take lessons, etc. However, it's very much a niche hobby - more than A local club it's THE local club. Part of me wishes that I'd have chosen chess, which would've given us an order of magnitude more opponents and materials, both online and offline. On top of that, apparently it would've given my son an additional way to gain social status at school. However, the truth is that we do enjoy Go more than chess, and have already invested quite some energy (I am beginning to be an intermediate with an ELO of around 1150).
There are some perks of course. The Go community is super nice (the joke goes that, unlike with chess, you cannot just go to another club to play IRL if you piss off your club members). It's so small that even as a beginner I got the chance to befriend the reigning Polish champion (and one of the very few European Pros, which is a big deal - they play almost on par with the Asian pros). He turned out to be a fantastical human being, if a bit intimidating at first (he will casually play 5 games simultaneously, maintaining separate teaching conversations over each board, and a bonus conversation about AI; then he will be able to write down every game on paper).
While I feel a hint of jealousy for the popularity of chess, if Go were to disappear, I would just switch to chess and have probably have 85-90% of the fun I'm having with Go (not to mention access to my father's vast chess library). So, the fact that young people enjoy mind games makes me very happy - I feel that playing chess or Go is genuinely good for you.
