If you honestly think this, you've spent too much time on very dismal parts of the internet.

Is it dismal to think that perhaps billionaires are not a net positive for society?

Yes, actually.

You could argue (you'd be wrong) that it's bad for them to hold onto most of the billions they earned, but arguing that Gates, Elon and Bezos have produced "net negative" for the world is incredibly dumb and cynical. They've obviously produced an incredible amount of value for billions of people.

It's not so much about "value" (or most likely "money") they brought to individuals but more about which way they steer society as a whole. When you look at it this way it's not as clear cut as you appear to believe

On the other hand people praising Musk &co as if they were done sort of prophets spent way too much time on another very biased part of the internet...

They are not prophets but seems they were at the right time in the right place to produce some world changing things. A cat can't do that.

An electric car for the top 0.01% of the wealthiest and an online supermarket (selling mostly counterfeit Chinese products) are hardly world changing in my book, at most they're "nice to have" and even that would only be true if we don't look at the negative side. People have to take a few steps back and look at the big picture, these things are shiny new toys distracting us from real issues.

The cat things doesn't matter, we humans have the capacity to alter the world like no other animals and so far we're on course to destroy most of it, and its life, by the end of the millennia. It doesn't matter what a cat can or cannot do, what matters is what we do, tech gadgets are fun and all but as I said, take a few steps back.

Tesla was producing electric cars far before Musk got involved and then claimed to be a founder.

Still, Tesla was not founded by a cat for sure.
