Well, it's just patently false. It may be the case in the mind of some in the echo chamber ... but as I seem to almost regularly need to remind on HN ... there is a whole world outside the party line view of what the world is like ... namely, what the world is really like. :)
Like I said, I agree with his conclusion that lots of kids still watch cartoons, just pointing out that his knowing a few kids who do isn't proof of this.
To put it into HN cliché phrasing: the plural of anecdote is not data, even if the anecdote matches the data.
I totally think you guys are right about me not having proof either. I think we both can say some people do and some don't, but a lot more younger children are spending time doing things that we once didn't do for those who grew up in the late 80s and 90s - people who grew like from this period of time should had a reasonable access to a machine - be it PC, gameboy or PS1.
