My personal take, however, is that, for crypto to go mainstream and the impact felt, the focus needs to pivot a bit away from Bitcoin. Yes, it is the first crypto, but at its present state, it definitely cannot fit into every area. This is my opinion, if you have something contrary, I will definitely love to hear them.
No, they do not need to "pivot" away from bitcoin. Just because it has some flaws, it doesn't mean that we will stop using it. Instead of running away from it, we can come forward and help develop it into a better thing. We can put forward ideas that will ease things for us but without causing much disturbance to the main protocols of bitcoin.
Again, those who knows about bitcoin will eventually learn of other altcoins. They will know when to use which coin.
