I like exploration of alternative theories about space and time, but from what I heard, Smolin's arguments are vague, confused and completely unpersuasive.
Ms Harris also seemed to have her doubts.
The whole thing reminds me of the Carlin's 'Hippy Dippy Weatherman"
The whole attempt to discover some 'deeper meaning' about time is vague, confusing, and irrelevant in my opinion. I'll always suspect scientific discourse where 'folks' can have any opinion they like and not be called a crank. Just my opinion. LOL.
