Yeah fuck that.

If you think people from a time where we're wrecking the environment, engaging in Fascism, genocide, and capitalism gets to say that future people who become furries are bad then you're not paying attention.

The wealthy only go to Saudi Arabia because it's rich, money has a gravity. Once Saudi Arabia is a poverty stricken nation the world's rich will go elsewhere.

Which is why they're doing stupid things like golf courses. No one wants to travel thousands of miles to a sand pit to play golf. And the water requirements of a golf course are expensive in a place like Saudi Arabia.

They'll always have at least some tourism simply because of Mecca, but I'm doubtful that they can sustain an entire national economy on that.

Yeah, and the oil money will be gone in 20 or 30 years, there's no time for all those huge megaprojects they're talking about to be built.

The Saudi citizenry mostly does no work at all, almost all labor is performed by imported workers who are kept in near slavery conditions. They don't have an economy outside pumping oil out of the ground, and they have no workforce trained to do anything.

Once the oil is gone Saudi Arabia will collapse to become an impoverished nation.

We don't know.

Is there an actual fixed number of things to learn? Or can science keep going and finding new things forever?

We're clearly nowhere near any limit currently, if there is one.

But if we don't go extinct and we keep learning will we hit a limit in 10,000 years? 1,000,000 years?

No idea.
