I think they will not survive in the near future because the problem of cryptocurrencies' regulation is becoming more and more serious so centralized exchanges can be in favor
That's the whole point of DEX. When government tries to manipulate and control the centralized exchanges through regulation and the threat of force the decentralized exchanges will provide the solution to the people.
Which one will you use?
The exchange that requires KYC and reports your trades to your local mob (government)
Or
The exchange that allows you to trade anonymously and without fear of confiscation or censorship?
The centralized exchanges are the ones doomed to fail, not the other way around.
