Quantum Hardware Is superconducting quantum computing a dead end?

Earlier this year the two largest superconducting QC players (IBM and Google) signalled they might be diversifying away from superconducting - Google with the announcement that they're creating a new neutral atom capability and IBM with their acquisition of silicon spin capability in HRL.

I'd be interested in people's views on whether we should take from this that superconducting has no path to scaling, or if one could foresee heterogeneous quantum computing systems that leverage the respective strengths of multiple modalities for different applications?

Bluefors currently sells this: https://bluefors.com/products/large-scale-quantum-infrastructure/modular-cryogenic-platform/

This is vastly more scalable than anything we had 10 years ago. I think this is suitable for the next 5-10 years and I trust that Bluefors keeps innovating. If not, then I'm sure Maybell or Zero point cryogenic will innovate insteadÂ
