If we are moving towards a society where we look more for meaning than for money we can very easily come to the conclusion that basic income wouldn't break the economy, but bolster it. Instead of doing menial labor to pay bills we'd try harder to find our way as artists, engineers and other specialized trades that offer fulfillment. Certainly some people will use their basic income to avoid work, but what is the percentage of that? I don't know many people who embrace boredom. Most people want to do something of value, and many people need to do something of value.
We are either approaching a reality we as humans have always wanted or shifting our societies desires depending on historical information(that I don't have).
Inching closer and closer to post-scarcity will be very interesting indeed.
