I would answer your question, with a question...
Is it the answer to what?
Even conservative economists like Milton Friedman suggested that something like a "negative income tax" could be a solution for people who are currently on a welfare, as it would still put the same amount of money in their hands as they're currently getting (via tax policy), but eliminate government bureaucracy that makes the process more expensive.
If you're asking if it's a solution to automation-related issues, I'd say that's a bit of a longshot.
People tend to think of automation as something that only impacts the "low-skill workers" (as that's largely the group it's impacted up until now).
But I think people need to consider the reality that it'll impact a much wider percentage of the population, and end up displacing people who a UBI payment simply can't accommodate (to the amount they were currently making) and that's when it'll get messy and we'll see higher levels of disgruntlement.
For instance, if we made a rule right now that says "Everyone gets $2000/month, do with it what you want". The person who works the grocery store or gas station or fast food restaurant will likely be pretty happy. Because, even if their job is automated away, they'll still have more money in their pocket every month than what they were making at their current job.
How does that start to play out when automation creates an algorithm that's better at detecting cancer than a trained and experienced radiologist who was making $275k/year (and devoted 10 years of their life to college, and paid back exorbitant debts as a result), when they get automated out of their job, are they going to be happy with $2k/month, or does having their job replaced by a $2k/month check mean that they're going to have to find a way to sell their house and completely change their standard of living?
The radiologist, or chemical engineer, etc... who gets laid off isn't going to be nearly as content with that 2k/month check as the person who formerly worked at the local BP station.
The resentment factor will kick in...it's just human nature.
