I really don't know if it is cool. Seeing the market saturated with mediocre (and worse) creations is more depressing than cool for me. And I feel like it's only lowering the bar, where people can't demand quality and those who create can't put in the effort because there's not enough demand for it.
I can spin a narrative whereby the app store fills up with fart soundboards, but famous artist (or team) is able to practice and later in life make really great app/game/art because they have a fresh, minority perspective. In the alternate narrative, said person (or team) wasn't able to build a portfolio enough for the first rung and pivoted to some other hobby/industry. Presumably we've already formed the assumptions that guide which narrative we value more.
While it does cause gaps in logic and nobody wants to be supporting a code base in a professional setting that was built with design/architecture as an afterthought, it's still cool that more people than ever can do something like make a website or a game.
