I don't know what that comment said and guess that it was something racist but from the context, who even cares if it was stolen technology? Better used to benefit more people in the world than hoarded by governments and corporations as a political weapon.

The Russians never invent anything

Literally the most prominent ethnicity of a country that was first to get into space.

Also, as a person with a math background, hearing that somebody says that is just funny to me in general (albeit, I am considering the usage of the word 'invent' as 'invent or discover' here). Like, have these people not heard of, for example, this obscure field of contemporary math called 'probability theory', the axiomatisation of which was done by Andrey Nikolaevich Kolmogorov, a Russian Soviet mathematician? I guess ideas such as 'measure' are too big for their thinking stoves.

I'd like to add: "It's not who does it first, it's who does it best."
