I totally agree.
For me, meals are the line not to be cross. And if you go this way to be quiet with your toddler, good luck changing this habit later...
On the other hand, I can say I am quite amazed with how teenagers use youtube and co to open their minds to a lot of different topics and learn about music, blockchain, innovations etc. My kids are way more cultivated and open to the world than I was at their age.
So, as you said, it all depends of the parents and how you find the right balance for your kid.
