It is now day three of war. I have more or less relized the scale and the consequences of the events and worked out the rough plan of my actions. It's going to take a lot of work, but I'll get through this. There are a few complications.

1) Russia can't buy chemicals from USA anymore. It makes it more difficult to do work as stuff that is made here is not great and what China sells is often quite shite.
2) Germany seized all the scientific projects with Russia, and there were plenty. I think the rest of Europe will follow along soon. And there are few facilities in Russia, most resources spent in the last years were aimed at getting access to foreign ones. Mainly, you guessed it, German.
3) If I happen to drop out of University, I get mobilized and sent to war. Which is not exactly what I aspire to do with my life. Killing humans is not on my to-do list and, I hope, never will be.
4) No CPUs and other components for the next 5+ years, probably. It's a good thing I use linux and pretty much any computer will work. My i3-8xxx should last me a few more years before giving up and by that time I hope to get the hell away.

Correction to n.4: China will import their computers, huawei and xiaomi and maybe others. I may upgrade to these. but who says China will keep getting their CPUs?..
