This is true. It's by no means garunteed that we will get to a point where effectively all the jobs are being automated. If we eventually get there, it seems likely the path will be gradual and prosperous enough that we can handle the transition in a way that provides for everyone. The dangers of the alternative route are real, but hopefully obvious enough that we can collectively avoid them.
You think the leaders of our planet would just wake up one day and walk back all the crap they’ve said for decades about dismantling the welfare state? And for what because we won’t be working? The whitehouse just added work requirements to medicare. That is the opposite of abundance providing for all.
Right now it is difficult for the average person to put themselves in the shoes of a homeless person. There are a litany of ready made excuses not to do so: "Oh it's the drugs", "They aren't even going to the shelter", "They must have mental illness", a variety of ways to say "I could never end up like that, if it was me I'd do better and pull myself out". These excuses evaporate in the face of a real automation wave where a large portion of friends and family you know to be hard working and intelligent are finding it impossible to find a job.
There will always be a relative few people with income. The business owners, property owners, asset holders, landlords, and so on. Those are the people who prices are set for, and who will participate in the economy. The rest of us? A lot of us are already essentially economically irrelevant in the grand scheme of things, and more and more are becoming so every day, even as they nominally get richer.
