Your question has many flaws:
I see the World is Going to the Way that no Middle men anymore!
Like decentralized banking the New era of living.
Decentralized banking is misleading term. There is no concept like decentralized banking. The closest substitute to this term is cryptocurrencies and few dapps providing online credit facilities. But since value of cryptocurrencies is highly dynamic, this model is not sustainable. In short, banks are not going anywhere.
Like uber and Even mobile apps where u can hire someone for the Job or u can get job anytime When u Want....
You gave the example of Uber. But tell me how Uber solves the problem of middle-man? On the contrary, I would say Uber act as a middle-man by bridging gap between customers and cab-providers. Uber receives payment from customer, keeps its cut and gives rest to cab-provider. This is classic example of how middle-man works. You gave entirely wrong example in the situation.
What about Middle - men?
If we Don't have banks anymore traditions ways then are the bankers Will be unemployed?
Bankers are not middle-man. Bank is middle-man which acts as a medium between those who have extra money and those in need of money. Bankers are mere agents of banking system. Bankers are not born bankers, they appear for test and pass requisite training to become banker. In short we can say being banker is a profession. If banks vanish (which is highly unlikable), bankers' profession will end too. But that doesn't mean bankers will go unemployed. Banking companies will evolve themselves into something else, banker's job will also evolve into something else.
Do you think life without middle men Will be better?
Very subjective question. Answer differs from case-to-case basis. There are areas where middle-men are necessity while there are areas where removing middle-men will bring more comfort.
