#117 - Productivity Alone Will Not Pay For This, with Forrester's Michael O'Grady
Graeme Scott sits down with Michael O'Grady, the forecaster responsible for Forrester's global, European and US technology spending forecasts. If you want to know whether the money going into AI can come back, he is the person who has run the numbers.Michael is from Manchester, has a maths degree, and spent the first half of his career on physical problems: modelling nuclear reactors, then modelling tyre dynamics in France. The second half has been business problems, through software management, portfolio management in pharmaceuticals, and fifteen years at Forrester putting numbers on enterprise spending.He starts with adoption, and the picture is more uneven than the headlines suggest. On US Census Bureau data, adoption among large companies runs around eighty percent in IT and around seventy percent in finance, then falls away through manufacturing and further still in administrative services.Then the arithmetic. Hyperscaler capital expenditure is running at roughly eight hundred billion dollars this year and consensus estimates point past a trillion next year, around two thirds of it on computer equipment inside data centres. Their remaining performance obligations, the order book still to fulfil, sit at around two trillion. His read on the bubble argument is more careful than either side usually manages: the demand is visibly there, which is why he does not call it a bubble today, but much of it comes from private companies whose finances nobody can fully see, and the compute being paid for now will not come online for two or three years.The centre of the episode is what he found when he tested whether productivity could justify the spend. He took the historical uplift from the personal computer and the world wide web, which added perhaps one and a half to two percent to productivity growth and lasted about twenty years before eroding. He assumed AI delivers something comparable, modelled it against US GDP out to 2035, discounted it for the time value of money, and compared it with the cost.It does not pay for it. On his modelling roughly half the return has to come from somewhere other than productivity, from what Forrester calls adaptive advantage: resilience, faster releases, better customer journeys, the ability to enter markets you could not previously serve. None of that shows up as revenue per head, and most organisations are not measuring it.He also walks through Forrester's jobs modelling, built from the knowledge, skills and abilities of around eight hundred roles combined with the Frey and Osborne automation framework from Oxford, and is clear that the number of jobs augmented is several times larger than the number displaced.
