His prediction that asteroid mining will end war on Earth and Musk will bring it to us
He didn't make either prediction.

The illogical: "thinking about...what forces need to be in play to take civilization into the next century." This is a future bias, in that essentially the future is always better.
We know the future will be different because the current lifestyle is not sustainable. Will it be better, worse or just different? If we don't actively do something it will be worse: We will run out of various resources and the changing climate will make many places very unpleasant. Musk is trying to make the future better, or at least allow us to keep the current lifestyle but in a more sustainable way.
How would the world look like without Gates, Jobs, Bezos and Zuckerberg? We would still have personal computers with operating systems, smartphones, online shopping and big social networks - maybe a bit later, with a different company name, but it wouldn't have changed much. They all had competitors doing the same thing.
Before Tesla, electric cars were like the Prius: Small, slow, with a short electric range, bought by people who wanted to be eco-friendly or at least pretend to be. Tesla's Roadster was elegant, fast, with a high acceleration and with a long range: a sports car. Tesla showed electric cars can be interesting even if you don't care about the environment, and suddenly other car companies looked at more powerful electric cars as well. Where would we be without Tesla? There is a chance we would still have only Prius equivalents on the road, but it is hard to tell.
For SpaceX we don't have to guess, we have a long history to look at. How did the space market look before SpaceX? ULA had a monopoly on US government launches with cost+ contracts: They had a monetary incentive to make them as expensive as they could reasonably justify. Their rockets got nearly no contracts from elsewhere due to their price. Arianespace launched most heavy satellites to geostationary orbits and launched government satellites from European countries. India and Russia launched smaller commercial satellites and their own government satellites. China did their own thing. No one had a big incentive for making launches cheaper. Once in a while some new variants were introduced but overall the market was quite static. Without SpaceX we would still have the same situation.
SpaceX entered the market and offered one of the largest rockets, at a price of one of the smaller rockets. They quickly got many contracts, so many that they needed years of production ramp-up to keep up with all of them. This year they got 2/3 of all commercial contracts worldwide, and they also get several US government satellites. Now everyone else is trying to keep up. Ariane 6, Vulcan, Vega C, Soyuz-5, ... In addition, SpaceX demonstrated that rocket reusability can save money. Before them no one was planning to reuse rockets, now everyone is looking at it. ULA, Arianespace, the Chinese, the Russians, India - they are all developing partially reusable rockets. Reuse is a must if you want drastically lower launch costs.
SpaceX did one more thing: It showed that rocket start-ups can be successful. And suddenly we have them everywhere. Rocket Lab has the operational Electron rocket, Vector Space Systems did flight tests with its Vector-R already and plans an orbital launch next year, Virgin Orbit wants to launch LauncherOne next year after test flights of the carrier this year, Zero 2 Infinity plans to launch Bloostar next year after test flights of the balloon last year, Firefly Aerospace plans a launch of Alpha next year, LandSpace aims at 2020 for Zhuque-2 after a failed launch of a smaller Zhuque-1 this year, and so on (this is maybe half of the list of relevant start-ups). They all have the same goals: Make rockets cheaper, make rocket launches more frequent.
Three companies plan to install LEO satellite internet constellations - OneWeb, Boeing and SpaceX. They need more than 1000 satellites to make that work. With the old rockets and their production rates such a constellation wouldn't work. It is SpaceX and the development they started that make these constellations possible. The constellations can provide internet access for everyone in the world - over 3 billion people still don't have that option today. You know the impact internet access had for the first half of the world's population. Now imagine connecting
the other half.
tl;dr:
Forget Musk's Mars ambitions, forget asteroid mining, forget the tunneling projects, forget Neuralink - although all four have the potential to be revolutionary on their own in the future - forget Tesla if you want. Truly global internet access will have a massive impact.
Edit: Missed Neuralink
