I mean, you can work for government, it's excellent (if underpaid) work. But they absolutely don't have the long term scale, focus, or investment to build something like Databricks/Foundry over several decades.
Which, they could - in fact, government (specifically meaning Civil Service) is the ideal environment in which to manage long-term scale, focus, and investment - it's just that private (in fact multinational) interests have weaponized politics against "government", which in practice means "good governance".
