Cost of building a tower is much more than something like rowhouses, multiplexes. Cities like Toronto and Vancouver bypass the "missing middle". So it's mostly single family homes with various "tower node districts".
I'm not sure Google knows either. "Smarty city" just smacks of vague buzzwordy-ness idealism. What is it exactly? Are you just going build some condos and stick some wifi around? How is that really different than any other modern city?
I just wanted an updated mac mini...not a "pro" model. Whenever Apple attaches the word 'pro' on a product it usually means "a fuck ton more expensive".
