> Or there are aren't enough jobs?
That's the thing about higher education and/or highly skilled training. It enables the creation of more jobs. (A job can be self-employed).
And to that end, we have jobs, plenty... but we don't have folks willing (or qualified) to fill them. This is inside the "bubble", but there's very few software companies that are not constantly hiring. We simply don't have enough qualified engineers to fill all the available seats. I'll concede that there are certainly fields where jobs are disappearing, and as you hinted, this is part of the "new economy". We need these folks (and our young generation) to gain new skills that are more useful in this new economy. Sure, many things will become automated, but we need folks to create the automation. (and no, I don't believe doctors nor lawyers will ever fully be automated, as these are not just knowledge/task-based skillsets).
> I don't need to take from you to give to someone else because what you offer (your labor) would no longer have value
This is not how an economy runs. The government can't print money to hand out, so it must come from someplace. This someplace is taxes, paid for by the workforce in majority (payroll tax + income tax equal about 80% of federal revenue[1]). If this workforce shrinks, so does federal revenue, which means not enough funds to support a BI long term (this is part of the reason a BI has never been implemented, even though it's a very old idea. We have to wait and see how it works out for the volunteer test nation in the long term...).
> Basic Income is easy when automation and clean energy are doing the heavy lifting
This goes back to my earlier point. We need fewer low skilled laborers, instead replaced with more highly skilled laborers. We need folks to design and implement the robots that will eventually build all these other things. We'll always have a human workforce - but the landscape of "work" is indeed changing.
