My perspective is just the opposite from the OP and all the commenters before me.
Automation, technology, any and all moves to make production and distribution more cost effective result -- in the long run, because of competition -- in more goods and services being put at the financial reach of more and more people. Which is a definite positive.
And the mechanisms to bring about that change all require new labor to make them happen. The demand for labor shifts, not disappears. We simply have to keep up with that in order to remain marketable.
No natural law says life is guaranteed. You have to earn it, and you have to keep on earning it.
And, as far as a guaranteed annual income is concerned... please keep the government's hands out of my pockets, thank you.
You are right in that skills have to keep up to meet demands, however if you've not viewed the video "Humans Need Not Apply," I recommend checking it out. You don't even need to have seen the video to know that the future is here with examples like driverless cars on the horizon and that development alone will likely affect the 3 million plus transportation jobs in a big way.
You are also right that to get it you must earn it, but what if there are only so many
opportunities to earn it? A company only needs so many decision makers at the helm, many of the physical jobs left can be worked by a trained robot, or replaced by automation. Truck drivers, janitors, warehouse pickers (my own current job), etc... Computers are even being trained to draw up reports with pertinent information found in seconds eliminating even white collar jobs.
With the new machines, we'll of course need people to direct them. We'll also need mechanics, designers, engineers, etc. Our vast labor pool is not going to be soaked up by the fewer and fewer jobs humans are required for however. We've seen that in the decades long shift from high school grads being able to find jobs in factories to high school grads being lucky to find jobs in Starbucks or Walmart. What happens when THOSE jobs are threatened by robotics?
You might be fine, your kids might be fine, and people around you well prepared, but we live in a country that on the whole I think is not prepared to handle a new reality of less need for human labor.
