Something not talked about often, but I wonder if basic income might lower the "applicability" of what people spend their time on. I know if money were not an issue I'd spend my time working on projects that sound fun, but might not have a path to profitability.
Money, besides being a motivator is also a signal to markets on what people want.
I've had a few landlords that just don't have any job at all and just ride off their cash flow. Boomer landlords of mine especially who got in on the property early before the market swelled in the last few decades just live like freespirited hippies. No other job, engaging in art or creative things, eating and drinking around town with their partner, and smoking a lot of weed. Even with this decadent living on their end and supposed enlightened disposition, getting simple repairs is still like pulling teeth.
This argument doesn’t get enough attention. There is a large population right now that has enough money not to work and - perhaps surprisingly to some - they do not engage in creative side projects for fun. They choose not to work.
The majority won't engage in productive tasks, but the output from the minority can be massive. Einstein wrote his papers as a side gig from his patent office job. It doesn't take many Einstein's to make up for a large number of slackers.
