It doesn't and won't. Automation is useful in certain areas but impossible in many. There is a reason why Tesla factories still have manual steps in assembling a car - it can't be automated away with reasonable costs.
Look at Switzerland (it is not UBI, but they have some of the highest labor costs): https://www.numbeo.com/cost-of-living/in/Zurich . A meal at an inexpensive restaurant which relies on low skilled labor (not just cooks and waiters, but the entire food supply chain) costs $27 USD. I am all for improving labor conditions though.
