Returns to data centers are currently very high. Whether that persists depends on whether capital owners satiate; if capital satiates, returns to accumulation fall and consumption rises, but for now data center returns are high.
Software is described as a particular kind of good with highly elastic demand: as it gets cheaper, people want disproportionately more of it, unlike oil, insulin, or agriculture where satiation limits total spending. That means software spending can keep expanding rather than automatically collapsing.
