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.
