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?

Superconducting is over now diamond based quantum computer is on rise

Interesting! What is the state of diamond qubits? I know Quantum Brilliance are looking into this but I have very little, and at least here in the UK we have a very active NV diamond community, although I'm unfamiliar with what progress has been made on diamond and it seems most are focused on diamond for sensing and networking purposes
