Depends on whose perspective you want…..
for business/ commercialism, it probably is a necessity. Lots of
concepts, whether real or not, are being cooked up to earn
consumer’s money these days.
one good example is this thinf called ‘energy water”. To me
water is water. So this concept is rather dubious.
Same thing for kindergartens…....
up to you to buy the concept being sold. For me, it doesn’t
work. Did Einstein or Thomas Edison have such things in the
past?
