there's no reason to suppose non-white people were/are somehow intrinsically less capable of innovation.
The GP didn't say that they were.
Not explicitly, but it is implied by what was said, particularly in context. European civilization invented all these great things and non-Europeans on their own would be mired in dirt and ignorance, therefore European civilization is humanity's greatest achievement, etc.
Somehow I completely missed the GP's last sentence. I agree, that was unnecessary and likely untrue.
If the bulk of technological accomplishments of recent centuries were made in European and European-derived countries in recent centuries... well, that's because those happened to be the affluent regions of the times, the result of being the ones that colonized and ran roughshod over the rest of the world. But there's no reason to suppose non-white people were/are somehow intrinsically less capable of innovation.
