Just look at a reference like https://en.wikipedia.org/wiki/...
R-12 (aka Freon) was phased out due to its ozone depletion potential, but it also had terrible global warming potential. The main issue is that it would persist in the upper atmosphere for hundreds of years.
R-134a is its replacement which has zero ozone depletion potential, but still a significant global warming potential.
Finding replacement for this, you see a lot of manufacturers accepting the risk of using a flammable gas and going with something like R-600a, which is literally just propane... not fluroinated, vastly inferior in terms of compressibility and its ability to carry away heat, but it works.
The real issue is industrial applications. I feel like that's largely glossed over and emissions are largely from industry, whereas consumer-level systems are just a small portion.

Of course it would help. Just look at a refrigerant chart for global warming potential. A lot of the older ones have already been phased out to reduce ozone depletion potential, but their replacements were almost as bad in terms of global warming potential, which we weren't as worried about at the time.
For example, R-12's high ozone depletion potential also had an extremely high global warming potential, but its replacements like R22 and later R134a are still relatively high for global warming potential. These are being replaced with R600a (isobutane, which is flammable) and R1234yf, which is a blend of gases that have very different maintenance requirements due to partial pressures (one gas can leak out over time but leave the others, making the mixture less efficient and then you'd have to purge and replace the entire charge, not just top it up). It's a complex issue.
As we know more about these gases, hopefully we can resolve this... Obviously the sooner, the better.

The meaning of "molt" is to shed hair, feathers, shell, horns, or an outer layer periodically.
Presumably this is a collection of the discarded husks and other detritus from our AI overlords as they grow and become more powerful.
It is your duty to consume and revel in it.

UBI can be a thing if we have an infinite resource to exploit infinitely. Like clean fusion power, or human kindness.

This is awesome! Soon it will be like the Star Trek "utopia" where all of us poor slobs are living it up on the government dime with access to infinite energy to do whatever we want, while a select few people get to fly around in space ships and beat up aliens. I can't wait.

Gross.
It's bad enough seeing the sheeple who are content with their task bar icons in the center. We don't need more en-Mac-ification.

They are dismantling the sleeping middle class. More and more people are becoming poor. We are their cattle. We are being bred for slavery.

Maybe they can swarm and suggest some Linux distros to move to.
