Partially displaced I think. The fact that DeFi sector solves the problem with banks centralisation, its real life usage isn't fully unlocked yet. These newly hyped about Metaverse will surely end up same fate with DeFi, what would matter is their real life utilities to stand up in crowd. We didn't even have mass adoption for BTC DeFi.
The use of DeFi in real life is pretty low till date. Only a niche market is present for this and the future use is still questionable. Majority of get-rich-quick type schemes are coming up as the only things in DeFi and NFT markets.
I do hope it will be for the better because the technological advances are supposed to help humans and not devour them. In either case, is used properly, any new or old tech can change the current economy by a vast amount, like bitcoin has started to do but whether these new "Fads" are going to make any mark of their own is still a big question to me.
Real life problem solving is lacking in most of the startups that come in the sector also altcoins and their newcomers. This is normal in any sector seeing investment. We should wait and watch before putting money in any such project.
