People already think in Satoshis. It has been this way for many, many years.

The lightning network on bitcoin is where most people should be transacting with bitcoin. It won't fill up with any number of users, transactions are instant(less than a second), and very cheap(even when bitcoin fees are high). Nearly everyone who talks confidently about how bitcoin can't scale is unaware of lightning and other developments over the last 5 years.
Their beepers DID go off.
Clearly, climate change is on the rise. It is absolutely a fair price to pay for all the advancement. For almost all of history, we were dying under 30 years, we are close to triple that thanks to technology and all signs point to lifespan increasing. For pandemics, even if we outrageously compare just the number of deaths, not even percentages as we should, many pandemics of the distant past were way way worse than the only one almost all of us have seen in our lifetimes.

I know you have it in your head that technology is evil or whatever, but that falls flat when you look up the numbers you are so afraid of. You are like a teenager complaining about how awful their parents are when literally everything you love and enjoy has come directly from them. I would not be surprised in the least if you are a literal teenager with how little you have heard about history.
It is honestly amazing how little you know of history. We literally had over 100 weeks with more casualties than the entire Russian and isreali wars combined back in ww2. And somehow you think wars are now worse. It's honestly mind boggling.
Also, it is absolutely undeniable that murder is way down. You haven't looked, and you can't imagine how far off you are. The same for pandemics, it's not even comparable. You are arguing that dinosaurs are smaller than most mice and it would be hilarious if it wasn't so sad that you are so sure of yourself and so completely wrong about something you refuse to research. It is literally so easy to quickly look up and find you are wrong.
I recommend reading "The Better Angels of Our Nature" by Steven Pinker. People love to complain about how much worse quality of life has gotten for people, but when actually pressed for specific ways it has gotten worse, they are almost always arguing from a complete ignorance of history. Lifespan is much longer, healthspan is much longer, rapes are way down, murders are way down, torture is way down, dying in childbirth is way down, incest is way fown, pedophilia is way down, starvation is way down, dying from wild animals is way down, wars are way down. Problems now for lots of the world are things like people bickering over who gets to be next to who when they pee and who called a "he" a "she".
This idea that the world is way worse than it used to be is absurd and just shines a massive light on how popular it has gotten to selfish brats completely oblivious of where we came from.
There's a great song about him by the guy that had an album with Ani defranco.
Yeah, technological progress has historically made life worse for humans.
There is a reason why you point to examples from years ago, that's because that is where you are still stuck.
Yesterday's AI is today's normal technology, this is just what keeps happening. Some people just keep forgetting how rapidly things are changing.
You'll join this "cult" once the masses do, just like you have been doing all along. Some of us are just out here a little bit in the future. You will be one of us when you think it becomes cool, and then you will self-righteously act like you were one of us all along. That's just what weak-minded followers do. They try to seem like they knew all along where the world was headed without ever trying to look ahead and ridiculing anyone who does.
Believe it or not, it can be and is used as both. If you have any other questions or things you think won't work, just ask! A lot has happened in the last 5 years, and most issues people have with Bitcoin have been long ago solved. It is incredible how much different things are now, lots of old issues(like dealing with 0.0000015 issues) are no longer a problem.
