Trouble with anything new in this world, it's only the problems which get highlighted, and the media make a big thing of this, since as far as they're concerned only "bad-news is good news"
Forums also tend to give a very skewed viewpoint, since it's only the people with problems who post with their issues.
The silent majority never post messages, as they don't have any issues to moan about 😄
Also, many people just look at smart meters from their narrow personal perspective, as solely a means to view their immediate usage, and many just can't be a*sed with this.
I think a lot more emphasis should be placed on the way they will be utilised to balance loads on the system, with the reduction of fossil-fuel generation and the move to greener energy sources, plus the increasing demand on the finite grid resources with the growth in EV charging
