Because they were broke and didn't have the resources to invest properly even if they wanted to.

That's not quite true -- they bet the farm on Zen, and that bet paid off. Which means that now they have the resources to also invest in AI. I'm fairly sure if they had bet the farm on AI instead of Zen or if they had tried splitting that bet they'd be bankrupt now.
