Agree with some extent but you can not expect any future without Centralized Exchanges.
Plus points - Easy to use, centralized so have someone to help you in compare to DEX, need not to be techie to use it, safer than unknown Dex, reputation can be known, platform for new traders, marketing of projects, tier 1 exchanges list reputed projects and chances of exit scams are less, rare rug pull in compare to Dex.
Minus points - No security, wash trading, shady supply, insider trading, favoring listed tokens, shady projects in name of IEO, No good market maker, All of sudden suspend deposit and withdrawal, Support system not so good, intentional delay on deposit of tokens to kill arbitrage, controlling market even BTC.

So now you need to decided how you balance CEX and DEX usage. Exchanges are also here for making money so manipulation will be there, it happens in traditional stock market too at large scale. Just i want them to be more secure and prevent hack.
