More people, more awareness about how money works, and more dependence on global investors.

Everyone invests so they can have more in the future, so yes, it's not crazy to imagine people will invest in a company that's growing without knowing any other details.

Why did it grow so large is the question. Why do some of these companies attract all the talent and grow so large and dominate the future is the question.

It's because we're all limited on time and greedy.

Valuation has no connection to “talent”. Do you really think NVIDIA has just ultra amazing employees that no one else does? No. It’s all smoke, mirrors and financial shenanigans. That’s not “talent”, it’s lack of scruples. For an even more obvious example look at Musk’s companies where the valuations have absolutely no connection whatsoever to the business fundamentals.
