Amtrak had a lot of fanfare around its fancy new trains that can go 160 mph, but it turns out that the limiting factor is the super-outdated track infrastructure, so the actual speed hasn't changed much, averaging 65 mph. Whenever I hear about an amazing new productivity improvement due to AI, I ask myself: is this the equivalent of the trains or the track? In almost every single case it turns out to be the trains. In most real-world systems, upgrading the "track" won't happen overnight due to a technical breakthrough. The bottlenecks are political, economic, and sociological.
