I'd play games, read books and do drugs.

It'd be different from today's state of affairs in that I wouldn't need to spend the majority of my waking hours reading stuff I don't care about and building things I don't believe need to exist in order to pay for a house I don't own. Healthcare would probably be more reliable and accessible too.

At this point though, I no longer believe this is anyone's future except the most fortunate of the fortunate, most of whom essentially live this way already.
