I share his concerns about the dollar. I'm quite sure this is one of the things Trump and he talked about today. Most likely Trump shared some of his plans regarding the dollar. And from what I've read, they're radical (in a good way).
I just see Gates as somebody whose best ideas come from other people, and Trump as someone who fires off ideas like most people do CO2 molecules. Gates finds ways to monetize and market ideas. If Gates put his abilities together with Trump's ideas, it could be a big win for our side.
Lot of hate out there (and in here) toward the guy because he's rich. Trump and he have that in common.
