We often quibble here about terminology, and this is one of the bees in my particular bonnet.
Like you, I always put "smart" in quotes when referring to energy meters, and I use the word only because everyone else does.
However, all of the other things you mention really are very smart (without the quotes) - using highly sophisticated and complex technology which was totally unthinkable just a small number of decades ago.
In contrast, all a 'smart' meter does (at least, at present) is measure energy usage (which we've been able to do for at least a century) and store the answers in a number of registers and then communicate those answers to elsewhere via a 'wireless' link (with a small amount of possible communication in the other direction) - activities that I would not classify as 'smart' in the 21st century. Any of the other things you mention are 'more smart' by a number of orders of magnitude!
