In a very rare twist of events, Aston is actually not child-like optimistic! 
Yep, I think it’s only a matter of time as well. Politicians will virtue-signal for PR purposes but I am pretty sure that they are using such surveillance systems for years. F.ex. we had these so-called “100 days of protests” in Bulgaria several years ago and then the cops got busted by journalists that dossiers have been compiled for every single person who attended them, utilizing face-tracking and face-recognition software.
And that’s Bulgaria! One small and – in general – a poor country. Imagine what a mastodon like the UK can afford to do.
