2006 - 2026: What are the most surprising changes to happen in major cities?

[hipster duck]

What I've noticed in Toronto, some of which probably applies to other major cities:

- the skyline, particularly along the waterfront
- increasing presence of people of South Asian and Latin American descent
- relative decline of hearing languages like Cantonese spoken on the streets
- along commercial streets, the replacement of retail with take out restaurants and marijuana dispensaries
- food halls
- the decline of small concert venues and dive bars
- bike infrastructure (bikeshare bikes, separated bike lanes)
- our commuter rail system being viable for things other than suburban workers coming into downtown in the morning and out in the evening
- delivery vans for Amazon
- nearly complete annihilation of the taxi industry and replacement with Uber/Lyft. Taxis used to be nearly as ubiquitous in downtown Toronto as they were in London or Manhattan, but all the different companies painted their cars different colours, so it didn't really register as a huge mass of identical cars. Nevertheless, hailing a cab was as easy as just stepping out onto any street corner and raising your hand.
