What Happened in the 2010s
I very strongly disagree with #3. Machine learning has not yet proved its value outside of a handful of key areas (image recognition, voice recognition/synthesizing, etc). I think it's entirely possible we'll look back on today as a kind of machine learning mania. I certainly believe there is plenty of room to build sustainable businesses without a machine learning asset (and the associated data collection), and it's in no way "table stakes for every tech company, large and small".
