The thread title is terribly misleading. Read what Kipchoge actually said and it does not read at all the way the title implies. His overall point is about how the world is changing and that change often comes about with advancing technology. Imagine a year ago if somebody told you that the London Marathon press conference would be done through a video call...nobody would have believed that, and yet that's the reality. Whether or not you like the fact that they did the press conference by Zoom, it's still going to happen that way. If you are against using Zoom or some similar technology, then you don't get to participate in the press conference and you get left behind. It's similar with the shoes. People can choose to not like them, but there will always be some advances that make times drop, even without the shoes, whether it's hats with ice cubes, better road/track surfaces, better fabric for clothes, tape that reduces drag, etc. Accept that the world changes and technology gets better or don't, but if you choose not to accept that you're getting left behind.
