This isn't the kind of technology that focusses on actually getting it right, this is a product meant to be sold to companies that need a way to off-load their legal responsibility of preventing children below a certain age from using certain features.

It probably works quite well in prepared demonstrations and with content that fits neatly in certain age groups. Those demonstrations won't include people with disabilities or quite mature children of course.
