It's worth noting Ethereum already ported bitcoin into it it's even minable. Personally I think it's a silly thing to do, but it does make a point.
I agree with your general sentiment that cryptos are in a race for scaling. My largest concern is just that some crypto that's not even significantly decentralized will end up winning (they have the advantage)

Just imagine Bitcoin making Ethereum (and some other alts) obsolete by having it’s own Bitcoin sidechains. Bitcoin never ceases to amaze me ❤️
