I can't agree with you mate, What do you mean about more dynamics? Uni gives alternative solution for the developers to get the decentralized exchange site that is fully transparent.
UNI didn't change a lot but it gives only another way for people to exchange their ethereum assets easily rather than try to send it first to the cex but the fees is also very high because it's totally depend on the ethereum network.
I do not agree with him neither. Sure there are some features of UNI that binance may never have, but binance decided to go with defi route and now have pancakeswap which is literally the same thing as uniswap but works with bnb instead of eth. There is nothing that would pass BNB right now with just new features, it is just impossible because BNB adds all those features in itself.
If you want to pass bnb you have to just create a hype, look at dot for example it passed so many coins and became very high ranked, not because dot is the best blockchain, we have seen better blockchains never get listed that way, it got that high thanks to creating hype on people.
Get that "buy this and you will be rich soon" idea into peoples minds and you will be capable of making a profit in the future very easily and get ranked very high, aside from that with just blockchain improvements, bnb will not be passed.
