My TV is on all day, SO WHAT

I have toddlers. The TV is on all day (yes, even before the quarantine). But they go play with toys, come back, go play with toys. We still do other things, but I don't get why watching tv is such a terrible thing. My kids have learned such a ridiculous amount of things. They're incredibly smart for their ages. At 1 year old, they both knew some phonics, all of the letters, shapes, numbers, colors, so on. NOT LYING. And I owe that mostly to their educational shows on YouTube. I'm an adult and still watch tv a lot. It doesn't make me a zombie. It helps me appreciate, relate to the world, be happy. I can enjoy the world out there while still watching tv when I want.
