Whenever I read tech news like that, I always remind myself how life must be awesome in southern US with no snow, lots of sun, etc...
90% of the tech will not work here is will work with limited efficiency.
Roof solar panels however I can see it picking up here. Don't forget that snow stick to our roofs here a lot due to the material they are made of. If they would be slick/slippery/non-stick, they would be clear for the most part. My roof will be due in 5-7 years and I'll investigate the solar power thing properly before going ahead or not.
As for car, self driving and what not... One can only dream of pressing a button in the morning, hopping into a warm electric car, be driven to work while we argue about the Habs in the Canadiens 2022 topic and sipping on my coffee. Car drops me off at work and goes to park itself in a car park outside of town where it stays, could be washed, charged if I pay for it until I call it at the end of day to drive me back home.
But that wont happen up here due to weather and shitty roads.
