"But it would require someone with deep pockets to put the investment in as the returns would not come until down the line."
For the big datacentre operators - the OSes are already there, all you need to do is run up an instance of whatever software you need on whatever platform you need.
The gains for them at this point are purely around _total_ compute per _total_ watt.
As we've seen repeatedly ARM when cranked up starts drawing as much as x86, but x86 has the advantage of overall platform integration and power usage - it's not just the CPU. RISC-V is still too immature to call on this
The moment ARM or RISC-V undercuts Intel by 5-10% in a server chassis, it's going to be game over for x86 in these datacentres. At 2-5% they'll be rolled over as systems age out and might have a chance to play catchup.
