It sad true that tech would make the world a better place (in some ways). But not because of the infinite goodness and wisdom of the first movers, who happened to entrench themselves at the right moment in time.

The same is true today. Eg LLMs have huge potential. What worries me are the sociopaths who draw the same conclusion.

I think the world is a better place if people are happier. Technology making bad and harmful things common and easy, is making the world a worse place. E.g. social media in the pocket. Technology causing more friction and annoyance is making the world a worse place, e.g. modern cars, modern computers. Technology causing people to lose their jobs is making the world a worse place (although it is arguable if general wealth and well-being in the west comes/came from robbing and enslaving other people, and cheap raw materials close to the surface). And so on, and so on.

edit: even new roads or bridges can cause worse traffic in general, see e.g. https://en.wikipedia.org/wiki/Braess's_paradox#Traffic

The cost of living is absurdly low. I do believe tech made it possible.

The only concern I have is greed from landlords and medical practitioners.

The cost of resources has plummeted, the cost of scarce things (land and medical licenses) continue to go up.

(Although limited medical licensees is a US corruption thing, its not inherent)
