A few hours ago I read an article where the founder of Cardano says that the crypto industry does not need Bitcoin for survival.
We shouldn't be taking the opinions of these people seriously. Their opinions don't matter in the grand scheme of things. This is exactly what I would guess an altcoin owner would say. I'm not surprised, not shocked, I'm not even angry. It's his view and even if I don't respect it, it's still his view.
Further, they elaborate these arguments through an example that in the old times a window was needed for computers to run and now the mobile phone does not need a window and can do good work. (actually showing the shift from windows to mobiles)
He just shot himself in the foot.
The mobile phones and other innovations were more sophisticated and technically more advanced than the windows and they've been working hard to keep remaining at the top, but these altcoins have not done anything more unique than Bitcoin.
The fact that you can't see the creator of Bitcoin sitting down to give an interview should tell us all we need to know.
