It'll be interesting to see how the Arab states will diversify their economies in the next decade. There's really not much to exploit there except oil, so unless they pump out enough money to basically rest on their investments in perpetuity I'm really not sure what to expect.
I would actually love to see Saudi Arabia take the lead on food engineering. They might lack fresh water, but they have immense amounts of land and sun to play with.
The only alternative I can see is a mass reforestation project.
Joke apart, how would they make money with solar energy? Oil is a very limited resources that can be transported very easily. Every country in the world needs oil but only a few country can supply it so the business model is extremely straight forward: export oil to the countries that has the money to buy it.
Now what is the business model with solar energy? Every country in the world has sun and electricity is hard to export over long distance so what are they doing with it ?
They do, but it only works as long as you can subsidize the locals with oil wealth to either not work or work in non-productive jobs.
The native Emirati population in Dubai is only ~300k while the total population of Dubai is ~3,500k. You can sustain that in a single city, but you can't sustain that throughout an entire region.
Saudi Arabia has a population of 32M with an immigrant percentage of 42%. To reach Dubai's ratio, Saudi Arabia would have a population of ~218M. That would be near Brazil or Nigeria. It would also require the country to expand to be able to support an additional 186M.
Neom. What do you think they are doing? They don't have to go to 218M but why shouldn't they? Whoever manages to have the next level of urban density first will dominate innovation and attract the brightest minds.
Yeah. They all seem hoping to do a Dubai, but there is no way that countries can run their economies on tourism and not expect their citizens to work in that economy.
