A few odds and ends:
-- Some dangers of living in a bubble illustrated. I've warned about this kind of thing.
-- An idea for space solar power, desalination and offshore platforms (some of my favorite topics), which I came across because of a comment at my Space Review piece this week.
-- A critique of Tal Fortgang's critics on "checking your privilege." Seems right to me.
-- Damon Linker accuses Neil deGrasse Tyson of being a philistine; his critique gets pushback (weakened by the misspelling of "Neil"). Having listened to Tyson's comments, I'm with the pushback (especially in that he goes on to discussion of the poet Rainer Maria Rilke; what philistine does that?).
