How do you define enormous? "It uses approximately 128 TPUv3 cores (roughly equivalent to ~100-200 GPUs) run over a few weeks". Also last time it took about a year for good replications to pop up.
While substantial, the resources here are well within reach of many labs, research institutes, and organizations. For this result this big, I'd guess we'll have 2-6 additional implementations in the next 18 months. The problem has been 'open' for 40+ years, so that's lightening fast!
Ex: Summit has 27,648 V100 GPUs (and those V100s have Tensor units). If you're saying that only 200 GPUs are needed to replicate the experiment, that doesn't even use up 1% of Summit's available utilization.
