They don't seem to be suggesting they use their own money. Just using their salary as a comparison. It'd be like if a trucking company related gas expenditures to employee salaries. If they had an employee that earned 80k but only spent $20 in gas, that would be odd. They seem to be suggesting that in order to prove their working efficiency, they should be spending a certain amount of company money on AI.
I don't agree with the assessment, but I do think it should be clear that they are not expecting that money to come out of employee salaries.
