Adoption changes shape depending on what you do: those who produce have public incentives that co-fund the intervention, a professional practice already has AI bundled into its software and underuses it, a retailer has cheap, available tools but only one in four have really integrated them, and a firm that moves goods can't find staff — tens of thousands of workers short — and uses AI as a lever for capacity more than savings, and a builder is the sector most willing to invest yet doesn't trust the output yet — in construction the barrier isn't cost but trust — and a firm in agrifood has two different buyers, the field and the processor, and is the most subsidy-dependent sector of all, with the new Agriculture 4.0 credit as the hook. Here AI adoption re-read sector by sector, with the numbers and the right lever for each.
