I've always thought both will happen. Some number of people are going to be hurt by this (they'll stop being productive) while others will use UBI in a positive way and benefit from it. What's up in the air is which way it's going to lean, imo. There still ought to be something in place to try and minimize the downsides either way. Personally I'd be a fan of making a work or education requirement to receive all or part of the benefits, so you essentially can't just sit on your ass and collect the money just for breathing.
