> Russia's high-tech industry is dead in the water

Completely agree.

> They won't recover for decades from the tech embargoes that started in 2014 and are very extensive now.

I hope they'll change approaches rather soon, 180 degrees, and will start digging out. It will still take time.

I don't see them making any kind of comeback any time soon, since they can't get any high-tech equipment from abroad. Which is pretty much impossible with current leadership and current political system.

Right, but they are in the stage of rapid changes, so current leadership may not stay for too long.

I would prefer they undergo a cultural 180 before they start catching up to the west or China on dual-use technology.

More than just sanctions, Russia is the sort of a country where if you start a company and its too successful someone with connections might show up one day with documents "proving" you signed it over to them for a fraction of its worth.
