There will be jobs, they just will require more education and/or skill than jobs currently require. This is always true any time civilization advances. The entry level jobs we have currently take more education and skill than jobs took 100 or 200 years ago.
My father, who died a couple of years or so ago in his late 80s, was a high school drop out. This was not a big deal in his day. It was not a mark of shame or a barrier to getting a job. When Lincoln was president, the average education level of your typical American woman was 2nd to 4th grade (IIRC).
Google stats for "big data jobs". It is expected to produce, directly or indirectly, millions of new jobs in the next few years. Trying to fill big data jobs is currently a challenge because of a skill short fall. It is expected to get worse.
You don't want to get that much education? Then pan for gold. Stuff I have read recently indicates we have only found about 5% of the gold in the earth's crust. We are increasingly using precious metals, such as gold and silver, in the electronics to which we have all become so very attached. Gold currently is selling for around $1100/ounce. From what I gather, about 1/2 cup of gold would weigh as much as a two liter bottle of soda and could be readily sold online for about 80% of the spot price, totaling around $60k in income. It is unlikely we will be able to substitute automation for human labor any time soon for finding gold.
Every single human that exists creates a need for labor. In human history, every time we successfully automate or otherwise dramatically enhance productivity, we raise the standard of living for everyone. When we do it stupidly and badly, we breed a situation that leads to a cycle of booms and busts. See historical civilizations dependent upon distribution of river water via some system in order to grow enough food. They develop a canal system and a complex bureaucracy to run it and every few generations the complex bureaucracy that runs it breaks down, causing the civilization to hit its bust cycle.
Edit: Let me emphasize that: The HUMAN piece of the puzzle breaks down, and the whole system falls apart. You are talking about intentionally trying to create that very situation with Basic Income. Automation cannot keep working without human maintenance.
I have no desire to live in a world where machines run everything and the last man who knows how to write the code that runs them or debug that code or do the repairs dies and the rest of the sheeple sit around waiting for it to fall apart so we can rebuild civilization from the ground up like a bunch of stone age cave dwellers.
We had better find a way to educate people and distribute the work or we are incredibly, amazingly fucked.
