Energy. Fossil fuels are finite and are getting expensive to extract. Fission is a good stop-gap, but again finite. Breeder reactors are supposed to help with that, but they don't exist yet. Renewable options are limited to geothermal and hydroelectric unless you want to invest in a lot of high capacity batteries. AIs will be dependent on electrical energy for survival, what else would they care about?
