I don't know who this Grant Peterson guy is. I just now read a few paragraphs about him at wiki. That said, it's very simple to understand in my mind who and what he is. He's a purist. And that's that. And there is nothing wrong with that.
I was once a purist. Fly fishing. But man, when the artificial plastic lures hit the market, I changed. I love a plastic lure. That said, I like to pedal a bicycle. And I don't think that I will ever change. No interest in e-bikes. None at all. No Di2 for me. Nope. Geez, if I keep going here, I might be just like Grant Peterson.?? Doesn't matter if I am or not.
I think the OP is fishing for support on his opinion. I'm independent. I'm not biting...
