Since the current NVL72 are still at the ~15%/yr failure rate it's not clear your new data center is going to have half it's compute in 3 years. If you're still running H100s they draw >10x kWh/Mtoken as new designs. All of these systems become dated, but not all of them require entirely new infrastructure.

If a ROM rack running a near frontier agent model at >10ktoken/sec costs <$1M (rather than $4-8M for NVL72s) and draws only 10-20kW (rather than 100-200kW), and doesn't require a completely new cooling and power system every time you update? There'll be lots of demand for GLM5.3 in a year.

What these don't do is TRAINING, they only do INFERENCE, but they could do it pretty well.
