People have jobs because they need things that can only be got via human labor. This is not a bigger issue at a root level, it is a basic fact that you are trying to deny.
I dream of a future where everyone has all of their basic needs met through technology, giving people the capacity to focus on doing the things they are naturally good at doing, things they enjoy, all on their on free time with their own free will. If you think about it, technology is nothing more than the rearrangement of resources to create tools which make our lives easier. Progression of technology is just a matter of how much better we get at creating these tools, and we are getting better and better and we will never stop. We will eventually have tools that make it effortless to satisfy all basic human needs. Automation is inevitable.
You are right that people will always have jobs, but the jobs that people have will also always change.
You are one of them: if you were not you wouldn't be reading this forum.
This forum is a particularly bad example to use, considering that it's more-or-less built on technology that is over two decades old (i.e. an online forum.)
I also agree with loh's comment here: "I dream of a future where everyone has all of their basic needs met through technology, giving people the capacity to focus on doing the things they are naturally good at doing, things they enjoy"
It would seem that the current system in place is what's required to get there, but maybe it's just slow to change for good.
All the fantastic gifts and riches in a modern economy you enjoy were made by Someone. You need to participate in and support the system by also making things for others.
> Not everything is jobs
Of course not. But it's something, and it's important!
It is the main factor for the vast majority of people. Anectada: I cannot nor could ever afford to 'live before participating in economy' - I needed place to stay, food to eat and some extra money to not feel like a bum. It takes wealth to enjoy life.
Ten years ago learning to drive a truck meant a long-term stable career, even if it's not the most glamourous. Today, we're discussing the short-term viability of automating that shipping system. Five years ago in Alberta, getting into a trade that was in demand in the oil industry meant a lifetime career with a pretty great salary. Today, the industry is on shaky footing and many will have to retrain.
In software, while it might not be near or certain, there are plenty of discussions about automating most projects since so many of them conform to common patterns and publicly accessible, free code already existing. We don't know any better how large much of the software development industry will be in ten years time. Many of those skills might be as obsolete as some IG "celebrity".
I think OP is at least correct in that you sort of have to weigh these things yourself. Sometimes that life experience in other facets will inform your future more than picking up a skill that is just enough to put you into someone else's employ. It's pretty difficult to know. You can apply any kind of probability measure you want, but the gaps in between any sound reason are just attempting to know the future before it happens.
