I don't think it's true Russia is ahead in hypersonics or nuclear power at all.
There's literally zero evidence for hypersonics whereas China has fielded at least their second generation of hypersonic gliders and at least first gen of cruise missile, Russia is at gen 1 for glider and gen 1 for cruise and I think this is giving them a bit more credit.
Nuclear power im less familiar with but China has got 3 different experimental reactor types running concurrently.
On renewables, computing, chips, cars, energy storage, digital infrastructure, cloud computing, shipbuilding, space. Yeah Russia is either far behind or getting lapped with over 1 generation gap.
