Don't get me wrong, I also can be susceptible to the ease of using a card or phone to buy something, over carrying a wallet full of notes and change. Like I said, they fool as by presenting it to us as a benefit, how we benefit from this or that.
I can also see the benefit of tracking your pet, especially if lost or in an emergency. But there are other ways to do this without putting in a chip. I wouldn't chip my child for example, even if it may help track them in an emergency. In the case of an emergency, these days nearly everyone has a phone, you also try to plan for the worst if something happens, have a meeting place, discuss evact routes, get to higher ground, what family members houses are closest in these situations, locations of hospitals and A&Es etc.
I only bring up the pet chipping, as it is being used to make the public comfortable with it and a common thing, so that when they move (they already have in some cases) to try to chip people, the majority will have been around it for the last 20 -30 years, and will say, "I've seen nothing wrong with how it has worked with pets, it's actually beneficial to me".
