AI's input is still sand: server farms and exponential growth

The hosts riff that AI's input is 95 percent people roaming on sand, and 5 percent people who think they are inventing better sand, but silicon micro-pellets are still sand: no engineering changes the fact that it shifts. A conversation about data farms replacing entire server floors every three to four years leads to amazement that the exponential growth curve shows no sign of leveling out.
