One signal

Revenue per employee is rising at top technology firms, but the picture looks different outside Silicon Valley, PCMag says. The article’s headline sums up one economist’s view: there are no signs of an AI payoff beyond the major tech companies.

That is a useful counterweight to the idea that AI’s gains are already spreading across the wider economy. The supplied account gives no name for the economist, so the view belongs to PCMag’s reporting, not a named expert we can assess here.

Discuss: Are AI’s gains genuinely confined to big tech, or is it simply too early to measure the payoff elsewhere?
