These are no more than just idle talks
I created a thread about a year ago telling basically the same, that "21 million cap is not so much written in stone". My main point was that what is done by one human being can be undone by another human being. But that thread was quickly filled with angry comments and I myself was just as quickly labelled as a heretic and traitor. I'm still keeping to the same view but seeing how miners are loath to accept changes that could even slightly undermine their profits (e.g. changing the notorious blocksize), this is utterly irrelevant what the so-called bitcoin elites are discussing now
You know what Satoshi would say? He would say "ya we can change it easy, just set it at x block" then he would leave and never address such irrational debate again.
No, I don't know
On the other hand, you don't know that either. Most likely, he left the scene specifically not to get involved in debates like this one. And that was a wise decision, after all. I don't think he would be quite happy to have his say ultimately ignored which would certainly be the case. If you have a half functioning brain, you can easily imagine how it might have happened, with miners not giving a fuck about anyone (Satoshi included) and anything but their profits
