In 2017 we couldn´t imagine that decentralized exchanges will ever overcome centralized exchanges in a daily trading volume. But thanks to UniSwap, it happened. Nowadays there are many UniSwap alternatives and new ones are created every day. I believe that in the future all people will move to DEXs, due to higher security, lower fees, and no KYC process.
I'm sure that Uniswap is just a hype, especially since they couldn't come up with anything new (maybe just a little bit 
)...Komodo made swaps much earlier... Bankor made similar Uniswaps erc20 swaps a long time ago...
