That last sentence is baseless, alarmist nonsense. The rest, makes some sense. We are definitely one of the most surveilled societies in the western hemisphere, but just look at the press here. If you think there’s a fear of criticising government in the UK, except in a (probably paranoid) minority, you’re deluded. Let’s also remember that an arrest is a very long way from a conviction, and others have pointed out.
Agreed regarding roll out - in the UK the grid is struggling to cope with rollout of Tesla and similar charging networks - there’s no way it’s ready to cope with the demand from widespread adoption of what BYD proposes, nor will it be for many years!
I think you pinpointed the ‘category of convenience’ phrase very well. What you say after that is highly subjective and there are no doubt many specifics that could be discussed at all sorts of levels!
Although even that is moving in the right direction via synthetic fuels to hydrogen and even some battery electric in public projects in the UK. Depends how ‘heavy’ we’re talking I guess. I wonder how long it’ll take the monster machines used in mining to make the shift…
One factor for me is the multitude of (sometimes semi-)isolated vendor ecosystems. The Thread and Matter technologies should eventually improve this, but right now vendor lock-in can be a problem and only the tech-savvy are going to actively seek out and deploy prior vendor-agnostic solutions like zigbee. Home Assistant is a great tool for geeks but a PITA for average Joe/Jolene, I think.
