No. It does not mean no one will ever work as a dishwasher/etc. It just means that the market rate for dishwashers/etc. will be higher. This would be due to the supply curve for labor shifting.
Certainly, some businesses will not be able to hire as many (or any) dishwashers/etc, but those that they do hire will have to be paid more. But that is a natural extension of decreasing the supply of labor.
The higher price that businesses will pay for labor will also push them to invest in capital (automation).
But it's getting to the point where dishwashing might not even be available as a job.
Right now, that's not the case yet. But it's not hard to imagine a future where it is.
Many menial jobs are getting automated and it's just getting worse and worse.
Soon, we will have to do something about it. These protests and revolutions are spreading like the plague. And social unrest is bad for everyone, including business. One day, it will become a necessity.
Just look at countries like Japan and Korea. Too many over-qualified people and not enough jobs. People are hired to do menial task like tearing tickets out of machines and handing it to people in a car. Suicide in these countries are skyrocketing because of hyper-competition.
In the rest of the world, these people don't commit suicide, they just gather into a big crowd and start protesting, violently.
There is definitely enough money to make work. The goverment just has to be smarter about allocating its budget.

In the Eastern Europe protests (Ukraine, Bulgaria, Romania, Turkey), people are protesting political corruption and abuse of authority, not poverty (in fact, I'll go as far as to say that many of the protesters are well-off middle class people, not the starving poor).
You still have to find the money to pay that universal basic income.
IIRC, the idea is to get that money by taxing capital and making it cheaper to hire people. As you indicate, getting it by taxing labor leads businesses to automate away labor, making it even harder to get that money from taxes on labor.
Think of it: that $5 an hour job currently costs a company $10 an hour or so. Without taxes on labor, they could pay $7 for a win-win situation. Even paying $5 would still be win-win, as the employee would have his basic income plus the $5 an hour.
