That's kind of different, though. That things start out as toys can mean many things. a) People create something for fun, it's fun and it turns out that after all, even if it wasn't intended, that thing actually satisfies a need better than current products on the market. b) People purposely want to make something that's seen as mundane, boring, or annoying more fun. Lots of failed attempt at gamifying work here, but there must've been some successes. c) People not so much create something that "starts out as a toy", but they create a toy, plain and simple. It's an entertainment product that is particularly well made and people like it because it's inherently fun. The underlying idea is simple: if we take an optimistic view of things, things that people do not inherently enjoy will either be entirely automated (and "disappear") or be turned into things they inherently enjoy ("toys"). So, if you want endless sources of ideas, think about those: a) How can you automate things people don't inherently enjoy (probably 90%+ of existing jobs)? b) How can you make things people don't inherently enjoy enjoyable? c) How can you make things people already want and enjoy (entertainment mostly), but better?
