I'm not even sure whether I would call this high-tech, having an autoloader is not new, they've been building and improving them for decades. To remote-control a turret, well, that is also not really high-tech, remote control devices were around in WW2, digital cameras are not exactly cutting edge technology any more, electrical turret drives also existed in WW2 already, so what exactly is the high-tech in simply having an unmanned turret? The difference to a western tank seems to be more about not having the low-tech in the form of the human eyeball in the turret anymore, which can be a disadvantage but says nothing about the required technologies.

And just because a nation is not known for something that does not mean that it is bad at it. When Germany reunited, the russian infrared missiles were found to be superior to the ones from the US when the german air force tested them, so much so that the new IRIS-T missile is based on them. It is unlikely that this is in any way reflected in western simulator game but that's most likely due to the aforementioned bias. The MiG-29 has had helmet mounted sights that allow the pilot to fire a missile at a plane he looks at and not just one in front of his airplane for quite a while now, the US only introduced them with the F-22 as far as I'm aware (although the Apache has had it for a while as well).

And one should not forget that a major part of modern high-tech is software and Russia has pretty good programmers even apart from shady business. The innovation is not just in the computer chip itself but in what you do with it.
If you ask random people on the street here about Swedish military technology, you could also conclude that Sweden isn't known for it and therefore the Gripen must be a complete failure. But then again what kind of argument is that?
