I'm self-taught as well, and I'd say look through the current job market and offerings, but don't worry all that much - teaching yourself IT usually nets you a considerable amount of transferable skills that you build upon if things don't work out in one field; you also learn to learn and get much more comfortable with switching branches.
The less volatile your branch is, the less likely it is to turn out to be a fad that you'll have to drop several years down the line at best. Crypto and blockchain, for example, were probably often recommended when the thing was on the rise, but that's nowhere near as popular and safe now; I believe the current AI hype to follow the same fate. Basically, look at the news and trends and be careful with whatever big and stupid corporations push for, praise, or massively invest in: that's usually nothing but good marketing successfully baiting the suits.
Web develoment is probably going to stay simultaneously volatile and relevant for decades more, so that's a good option. Embedded development shouldn't be going anywhere either, although that's more low-level and intimidating, but it can be fun and stable and pay relatively well. I hate the smartphones industry and can't really say much about Android or iOS development, but I doubt it's doomed or anything.
So far, it seems like not following whatever Elon Musk or other billionaires tell you is the future is a good bet.
I still live in Russia and want to offer a bit of an optimistic perspective.
First of all, Putin and the officials siding with him one war or another have been fearmongering a war with Europe, the USA, or even the entire NATO for years already. Granted, they did the same with Ukraine prior to the invasion, but I doubt there's any decision-makers left in Russia that genuinely belive they can swing at NATO and expect anything else but a swift and painful defeat: the amount of resources dedicated to the current attempts to do anything in Ukraine would make it even harder to launch a new offensive, let alone defend anything.
Arguably, fighting Ukraine, Russia is still fighting mostly Ukraine, albeit with significant aid from its allies or at least Russia's opponents; as reluctant as the EU, the USA, or NATO (or some of their counterparts) may seem to ditch the political ratings for either coughing up more resources or even restructuring to produce them, one tendency of our species remains strong: we do act when it's about us, when it's seemingly too late. Ukraine, for now at least, probably doesn't feel like an integral part of Europe or NATO, maybe some even still believe the country to be that similar to Russia, which, combined, explains the rather cautious approach in terms of providing more lethal aid.
If Russia attacks, say, Moldova or Lithuania or Estonia or Latvia or Poland or Finland or anything else (other than Belarus, perhaps), nobody is ever going to think of it as of some kind of conflict between neighbors that somehow seems more complicated than it actually is (partly because both neighbors are slavs and tend to have somewhat nuanced, rather than obvious differences, I guess), and on top of that, any doubts like whether it's possible to wear the Russian army down by dripfeeding supplies to the ones that fight it, or whether Putin can be appeased, or whether Putin will calm down after "reclaiming actually historically Russian land", or anything like that - all of that is going out the window and people start acting, fast, with the combined might much greater than Russia is managing to muster now through elusive contraband military imports and making use of decades-old equipment and economical manipulations.
And in a conflict like that, who's going to side with Russia, against the much bigger dog of NATO? Anyone who joins on the Russia's side gets at the very least sanctioned to smithereens in the event of an actual war, and neither China nor India can have that; some of the dictatorships from the middle east may try, but I doubt they'd want to give NATO a proper excuse.
Putin is a gopnik and understands only the language of clubs and stones - the powers that Putin chose to call his enemies not only have bigger and meaner clubs and stones, but have more of them, and have the means to get even more. He might have attempted something had he actually conquered and held Ukraine, but not after this kind of reality check; he's back to being the strong wife-beating alcoholic that sits tight when a real threat looks his way.
