That's a useful number. Just yesterday we had an announcement of an open source system you can train with one GPU on a desktop for simple models. That could usefully use 16 or 24 GPUs, but it's not like you need a whole data center. It doesn't look like this is an industry with excessive monopoly potential.

The real issue for machine learning is that it lets you build systems that optimize for some metric. That's what corporations do. I've been pointing out lately that the ethical problems for AI in the near term look very much like those for corporations.
