It's probably not a good idea to tell someone who has been studying something for half a century that she is making a 'broad generalisation.' I'm also South African, by the way, so I probably know a little bit more about Musk than you do.

That said, let's look at what he has actually done.

1. In order to produce the batteries that drive Tesla, rare earths have to be mined. The degree of chemical pollution that mining makes is just as dangerous, if not worse, than that produced by fossil fuels. I suggest you google how the mining of rare earths harms the earth.

2. In producing cars, along with other car makers, Musk is using plastics and metals. Plastics are made from oil (a fossil fuel) and the chemical process to do so, spews harmful chemicals into the air. We are running short of metals, and in a generation, there are going to be no more metals on this earth. The real solution is public transport - not personal ownership of cars.

3. The degree of toxic pollution that is shooting into the air from the rockets he is sending into space is contributing heavily to climate change.

4. He invested in crypto currency. That uses up massive energy - enough to power dozes of cities on this planet. How is that helping prevent climate change. Every single activity Musk is involved in is contributing (heavily) to climate change.

5. He is a racist who is being sued for abuse of his African labour in America.

I could go on. However, for the sake of brevity, I am going to keep this short.

21% of CEOs are fully fledged psychopaths, whereas only 1% in the general population is. In fact, it's virtually impossible to generate that kind of wealth in business without being willing to trample on people. Yes, there are rich people who don't trample on people - most of them are artists. Business? No.

More than half of existing businesses are selling or producing products that produce toxins in their manufacture. How does that benefit mankind? If you had to take your local store selling various products in his store, probably 80% (counting packaging) contain plastics which emit terrible toxic fumes (I studied materials and texitles at college).

I cannot think of a single entrepreneur who has solved any problems.

In the interests of full disclosure, I grew up in business and was a child of privilege born into a household with three full time servants, private schooling, etc. I don't think the rich are what you think they are.
