Let's not be confused here. Specialization is what allows for free time. If everyone has to farm and hunt, that's all you'd do. Specialization is a good thing for humanity and diverse institutions and industries to arise.

I work as a software engineer and I'm also one of these people that just gets a kick out of making things. So I'd probably do some more of that, just not for an employer. Even more contributions to open source would be likely as you've already highlighted.

Would probably build more physical machines/contraptions/electronic doo-dads that I don't have the time or energy to make today. That and I'd probably make more music, or more accurately, finish more music.

Probably grow more vegetables too, but currently that's limited by space anyway.

I would cut cars in half and weld them into the other halves of other cars

I'd still be a programmer. I'd work on open source projects 100% of the time. It's something I love to do.

Man's got to eat though. I still work in an area that makes the world slightly less shitty though, so it's not all bad.

Humans do not like the same thing over and over every day.

Speak for yourself, I like routine and being rewarded for working hard.

I'd have more time to become a better artist.

edit: what the fuck was that unwarranted shitty comment.

I run a goth night once every other month.
I visit friends quite often whenever I want to.
I get up and start my day when I feel like it.
I play with code and build web toys.
I'm a freelance IT guy. I could, if I wanted to, earn a lot more than I do, but my time is worth more than money. It is possible to do, even in this world where everyone is told that you need a 'career' and to work for a company, although a lot more work is needed to freeing other careers from the obligation of the grind.
Don't give up hope, unionise, demand respect, ~~buy a guillotine,~~ and keep an eye out for a way to get what you need and to contribute to society or your community without signing your life away.

(Yes, some people will never get the opportunity. And that, frankly, pisses me off no end. But don't lose hope until you're dead.)

I like my job. It's not a hobby, but it also ensures I don't burn out in my hobbies, which happened when I initially tried to make a hobby my job.

I'd rewrite the game engines for Command & Conquer games so that they could be modernized.

It's a perfectly doable task, but not with the amount of free time I have.

I would be doing more programming and more open source work. I would also spend more time doing physical activities like sports. I wouldn't mind doing gardening for anyone, I also wouldn't mind automating all their systems. Definetely I'd sleep for one extra hour.

I think I would travel or wander a lot more. Not in an instagram backpacker kind of way, just in a dawdle from town to town road trippy kind of way.

I'd do what I'm doing now but I'd be helping hospitals and schools instead of companies.

I would sleep a lot more, that's for sure.

Produce documentaries, develop a video game

If I wasnt working a job for money I wouldn't be doing anything that contributed to making food or providing infrastructure. What I did with my time would probably be considered useless by society and that's why I'm not doing it as a job currently.

Why is there so much communist content on lemmy?

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

Make art and hike more.

Id play more guitar and more piano, and record more. Id take pictures hiking and take videos and stuff. I'd fully automate the mundane from my life, finish my self hosting projects.

I'd be healthier, overall. By a lot. Mentally and physically.

Basic research. I left basic research because research in academia is a lost cause, killed by lack of funding, hyper toxic environment, rat race to the bottom, mafias and corruption.

It is so bad that I feel a much more morally cleaner environment working in finance.

I would go back doing what I used to do, but without the baggage that forced most of us to leave

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.
