There is a different danger however — after about 8 years the annual fee went from about $15 to $60.
That is exactly the point krageon is making. If you have a .so domain (or .earth like me), you need to have a backup at least, so you can still access things like a normal human. My @gmail.com address have been used for this, but seems I'm gonna have to get yet another domain with a normal tld so I can stop using the gmail one for when .earth is not correctly accepted.
I've had the same .org domain for around 15 years now. Except for the coup we've seen last year where somebody tried to buy it privately (thankfully averted, I believe), I've see no price hike over time.
That part is probably not a good bet, as life can go in unexpected directions.
Some country providers (eg .eu) only provide service to their citizens, so if you move country or otherwise become "not a citizen" they'll terminate your domain. As happened recently to the UK holders of .eu domains. :/
Probably better to pick a .net/.com/.org domain, for (hopefully) longer term stability.
Also .org falls under US influence, which may not have worked out so well had you been making this decision in Ukraine a decade ago
Very much agreed on .org.

Ahhh, hadn't realised that. Though I'd suspect .com and .net would be in the same position as .org in that respect.
