What about DeepMind? They are the biggest concentration of Neuroscientists in the world and their founder doesn't dismiss the idea of a "singularity".

But we may have a problem in definitions too. I think most people just mean computers have taken all the jobs and are inventing new healthcare tehnologies, etc. Some silly people who write silly philosophy books do think that super autistic cat video hungry AIs will turn every atom in the universe into computronium but I don't pay much attention to them.

Isn't it inevitable the SpaceX will (and already does) dominate the entire space industry?

Won't it be cheaper to launch on starship than anythign else even for very small payloads? Yes, I know about RocketLab but I wonder if they will be able to survive once starship is up and running.

What did you learn from it?

None of my math books are as obtuse as it is. The equations are presented on their own without explanations. On that page alone they're using quite a bit of mathematical notation that I, at least, have never seen before and I suspect it's largely unnecessary.

What did I expect? I expected a book that explained the concepts in plain english as well as mathematically. I expected the authors to be mature enough not to heavily decorate every single equation with as much mathematical notation as possible. Sort of like how bad coders make their code hard to read. That's the vibe I'm getting from the book.

I feel obligated to interject here as I have not read the book OP linked to but I have attempted to read the paper weight calling itself a book that you linked to.

I have it right here actually. It's basically total trash. They claim to show you how to do the math but at the very best all they do is restate random formulas without any explanation. It's not even good enough to serve as a refresher if you know the math. It relies very heavily on you mentally decompiling mathematical notation. I can't believe I got fooled into buying that book.

If you just want to learn the math there's no easier way than to pick up some math books from half price books. They're $10 a pop. It's an affordable way to learn at your own pace.
