Will any other blockchain network ever break away from BTC value?

Hi guys. I’m just wondering what people think about this topic. Normally every crypto currency follows the price of BTC, but I’m just here wondering if that will ever change.

There are networks like Solana (imo) that function amazingly, are cheaper, and are safe (unless you’re reckless or naïve). Why do all cryptos still follow BTC? Why haven’t they separated from Bitcoin and done their own thing yet?
