This would be fantastic news if the content was anything worthwhile. At the end of the day, I'm not sure I care whether the kid is watching commercials or some other inane show. It's still passive consumption.
Personally, of course I want less commercials. But being able to consume more per minute isn't necessarily a good thing, IMO.
My kids watched a show his morning which explained where eggs came from, and what happens when they are heated - how the proteins change shape, how the outside heats faster than the inside, etc. Also how bread is made, both manually, then showed automated kneading (this is a show aimed at under 6s, so anything beyond proteins changing shape seems excessive)
Yes it's passive, but it's still better than brainwashing then to buy McDonald's
