If you, the director of toasters at an appliance company, convince the higher ups that there's a market for smart toasters, then you get to hire an entire new team of software engineers to make the smart toasters happen, which inflates your headcount and budget, which makes you more important, which makes you more likely to be promoted, which is exactly the kind of thing that motivates you, because if that wasn't what made you tick, you wouldn't have become the director of toasters at an appliance company in the first place.
