Without capitalism, I'd probably be serf like my great-grandparents were. There's a lot to criticize about capitalism, but it's still an improvement on its predecessor.

I'd be that guy that makes all those useless inventions, except they'd be incredibly useful to me and like 2 other people.

You can do this right now, OP. If you don’t like living in a society just fuck off into the wilderness and do you. There are enormous swaths of land in this world where nobody will ever bother you. What’s stopping you?

There's a couple of countries without capitalism, you could try to live your dream there.

I too dream of this same future:

Quoting this:

"In DACs, knowledge, creativity, and innovation are communal properties. Whether it’s a new AI algorithm, a more efficient building design, or a breakthrough software update, all are shared freely among the network of DACs. This community-wide open-source approach fuels rapid progress and the spread of beneficial developments."

I would contribute to any activity that would ensure capitalism wouldn't start existing.

I also jump around with this. Like I would definitely read more. But there's a part of me that would love to write books. But also male music. But also paint. Basically I would do something in the realm of art.

I wouldn't mind having a part time job doing something physical. Like I used to work at a warehouse for a medical supplies company. It was probably one of my favorite jobs. I could see myself doing that again. Gives me a reason to get out of the house, be active, and people will always need the supplies. Ironically I lost the job because we got bought out by one of the world's largest corporations so they could make even more money, and they closed us down. So I lost that job because of capitalism.

Reading. I have lots of books I want to read but not enough time / energy to do so.

Im fortunate. I love my career. I've been doing since I was 12 what I do for a living now at 39. I'd still do what I do if income were a non-issue.

With that being said, I'd probably only do it three days/week or so, being able to pick a more realistic balance between productivity and burnout would be great. I'd also spend that time making something I want, for me, rather than doing what I'm told. I feel like that's significant here as well.

Go hiking everyday

What would allow that isn't communism, but a "post-scarcity" society, much like Star Trek TNG. A lot of what we take for granted can only happen thanks to the commercial logistics of fucktons of materials going around.

I'd devote more time into programming, performance optimization, processor architecture and computer graphics. These things are still "magic" to me and there aren't many resources, especially on the "bare metal" graphics part of most recent parts. Once I figured it out enough to feel confident in passing that knowledge around, I would do that in english and portuguese

One thing that I'm already doing thanks to my job giving me a decent salary for only 20h of work is my own game project. Something that I'll probably end up selling, but I'll probably be the first to release a pirate/free version of it, too.

If money weren't an object and I didn't have to worry about rent I would love to bury myself in math, chemistry, earth science, medical science, language, and systems development studies. Then I'd spend my free time sharing what I learned with others who want to learn, focusing on under represented. I'd also do more outdoor sports.

I would spend my time the same way. Honing my specialization to increase benefit to society. I love software development!
