Software is going to pile up because developing it is now cheap.

It won't, because right now we're busy exhausting the vein of good-ideas-we-wanted-to-build, and that's the source of all the good stuff you listed. When that runs out you'll see teams building any old crap because building is cheap, and learning that experimenting by putting any old crap in front of users is a fast way to burn goodwill and brand loyalty.

You still need good ideas and the taste to choose which to put out there over the bad ideas that people actively dislike.
