This seems a bit of a stretch of a claim to make. In what ways would you say that Russia is a decade behind?
I visited Russia a few years ago. Commercially, they have all the same technology we have (for me, in the UK). Like us, they outsource most of their manufacturing to China, but internally they produce software equivalent to (or to be honest greater than) what we produce. The difference seems to be that a lot of Russian software, websites and apps are more local, which gives the illusion that it's not as good. Google is multinational, whereas the equivalence Yandex sticks to Russian and Slavic language countries. I was actually quite surprised to see in some areas they are ahead in digitising things (government services, payments). I expected the opposite.
Whatever software you can think of originating from the US, UK, or wherever, Russia has an equivalent. The major difference isn't the technical ability, but the commercial and cultural reach of that technology. Most of the world is happy to use Facebook, except Russia (and some others) who uses VK. We don't use VK, because it's Russian and we already use Facebook. Google, Facebook, Twitter, Uber (all artificially high value commercial products) have Russian equivalents. Sometimes they are even combined into one (Yandex has an Uber-like service within it). And when it comes to hardware, none of us are particularly strong with that. We all designate that to China, who sells it to all of us equally.
Whenever we hear about cyberwarfare, cybercrime and exploits, we usually pin it on Russian/Chinese speaking hackers. Russia seems to have better primary, secondary and tertiary education in computing, and, like the rest of Eastern Europe, produces many of the better programmers (something you can see in open source communities). From discussions with Russians, the level of maths, science and computing education is higher at a younger age than it was for me in the UK. Quite a lot of what would be A-level (18) Maths in my country was taught at Russian secondary school level (16).
In warfare, Russia has made fools of themselves in Ukraine, but on the other hand war is (sadly) the greatest contributor to military evolution. We see that with the introduction and evolution of drone warfare. Our UK Challenger tanks have been disabled and destroyed by far lower cost drones. All the technology associated with that (comms, jamming, avoiding jamming, self-targeting) is being rapidly developed by both Ukraine and Russia on the battlefield right now.
Where exactly would a decade back put them, technologically speaking?
