One where the rich pay more tax then they currently do now. Also slap a carbon tax on these fuckers and use the cash to fund climate mitigation / adaptation.

Sadly, it's purely a dream. Humanity will reach extinction levels before any type of reorganization and rebuilding may occur. Only then can we hold hope that greater minds recognize that the greater good for all equals a better community and society.

I know you don't want me to look backward....however, IMO: humanity missed the boat at the end of WWII. If humans couldn't work together for a collective betterment for everyone, it'll never happen without a complete reset of the human species.

Wall-E. I get to be the robot

I don't dream much but I would like to live in a world where all the information published is free to modify and share (i.e. all the research data, hardware assembly instructions, firmware, microcode, software, books is copyleft). Intellectual property exists only as share-alike materials, you must publish the internals alongside with the end-user product (e.g. you can buy a CD, or download a content online). All the software is open-source, copyleft. Paywalls can only exist to cover infrastructure costs, you can still copy the content that is behind the paywall as long as you include the original author. This would break all the walled gardens of information.

Also, no dictatorships.

A world where all humans are autistic.

It wouldn't solve everything, but at least there wouldn't be room for chronic reification, useless charismatic narcissists, Cartesian dualism, etc to become big issues like they are in our world.

Syd Mead and other sci fi concept artists deserve their own lemmy community.. tons of visuals for this idea out there

Iain M. Banks' Culture

Totally ideal? Green energy robots automate all the stuff humans need (food, water, shelter, sanitation, etc.) so that no one has to work and people can do whatever they want!

UBI that is linked to the average income. So the more people work, the more everyone gets every month and vice versa. Make it so jobs are not necessary but available to better help humanity or whatever since machines will be able to provide most if not all the labor.

My ideal world is one where the population of humanity exceeds 10trillion, but the population of earth is <100,000 permanent residents with yearly visitation from tourism etc exceeds 100million thanks to the series of space elevators that have been built. The majority of humanity are living in space at various Lagrange points in O'Neill cylinders and at least a quarter of humanity are in living in generation ships traveling to distant stars many that are >10pc away.
The Asteroid Belt has been mostly mined out though that isn't much of a problem as fission/fusion generation supplementing the solar dyson ring has transformed us firmly into a type 1 civilization.
