2050 is not that far off. Liberals always think the near future will bring incredible miracles. The truth is progress is a lot harder and slower than an impatient liberal would like.
Per #6, those for whom technology is magic* often fail to grasp that just because something is individually available doesn’t mean everyone can make the transition in short order. It is precisely the _individual_ choice to convert which makes mass transition possible thru supply-and-demand; without that choice (not compulsory) the supply-and-demand process doesn’t work.
(”Any sufficiently advanced technology is indistinguishable from magic.” Smartphones and solar panels are nothing more than scrying-magic glass slates to them.)
