It looks like (especially) Barcelona and Amsterdam at least have some sensible approach wrt 'smart cities':

Toronto OTOH, holy shit.

“The genesis of the thinking for Sidewalk Labs came from Google’s founders getting excited thinking of ‘all the things you could do if someone would just give us a city and put us in charge’” - Eric Schmidt

Toronto is getting everything you'd expect when you collaborate with Google:
a dystopian nightmare

Came to that article from The Intercept from https://theintercept.com/2019/01/28/google-alphabet-sidewalk-labs-replica-cellphone-data/ which was linked in the article from De Correspondent.

"No Google data is used." claims Bowden from Sidewalk Labs
Further down the article:
"data is sourced from 'Android Phones and Google apps.'" and "based off of Google data."
Who would've thought Google is lying ...

Relevance for this thread:
'Smart Cities' is better marketing.

If you're not careful like Barcelona & Amsterdam, you'll get your panopticon.

"With Rekognition*, a government can now build a system to automate the identification and tracking of anyone. If police body cameras, for example, were outfitted with facial recognition, devices intended for officer transparency and accountability would further transform into surveillance machines aimed at the public."

police body cameras for officer transparency and accountability = better marketing

* Amazon service for facial recognition.

That blog post is linked from https://theintercept.com/2019/02/08/jeff-bezos-protests-the-invasion-of-his-privacy-as-amazon-builds-a-sprawling-surveillance-state-for-everyone-else/

"In a separate advisory, the ACLU said of this face-recognition software that Amazon’s “marketing materials read like a user manual for the type of authoritarian surveillance you can currently see in China.”"

Well, this is a surprise ... it turns out I was way too optimistic with my 5-10 years 😕

Lots of Americans seem to love Amazon and Jeff Bezos as he is a self-made billionaire.
Mass surveillance is indeed quite lucrative :-(

Ring CEO Jamie Siminoff emailed out the company’s new mission:
use consumer electronics to fight crime.
“We are going to war with anyone that wants to harm a neighborhood”

Ring is a company now owned by Amazon.

https://theintercept.com/2019/02/14/amazon-ring-police-surveillance/

"Ring products come with access to a social app called Neighbors that allows customers to not just to keep tabs on their own property, but also to share information about suspicious-looking individuals and alleged criminality with the rest of the block."

“The Neighbors App is the new neighborhood watch that brings your community together to help create safer neighborhoods”

That's better marketing for you.

"A Ring video that appears to have been produced for police reveals that the company has gone out of its way to build a bespoke portal for law enforcement officers who want access to the enormous volume of residential surveillance footage generated by customers’ cameras."

This site is called the Ring Neighborhoods Portal

"Not only does this portal allow police to view Ring customers on a handy, Google-powered map, but it also makes requesting customer surveillance video a matter of several clicks."

"Police can select the homes they’re interested in, and Ring takes it from there, creating an auto-generated form letter that prompts users to provide access to their footage."

Technically, you can deny that request ...

“the portal blurs the line between corporate and government surveillance”
