Bank is for the people that is saving their money which means the people are letting these banks hold their money for the future use. It is for fiat and not for cryptocurrency, so what will be the reason that banks will disappear because of bitcoin? Even if bitcoin is used by half of the world population banks will still exist because people are using real money. All the people might have their own bitcoin wallet, and that will not affect the banks.

From my standpoint it is still a little farfetch that it can out stand banks since the latter had already build a very strong foundation when it comes to currency/money itself. We know that the bitcoin industry growseveryday, we can't expect anything to change in just a day but it depends on the development as days passes just like how you earn money.

As we can see that the new generation is more into the digital way
We are going to enter a new modern era where maybe in future because of a high potential crypto currency like bitcoins may overcome fiats
What happens when people start buying bitcoins instead of saving money in banks
Obviously one day they will come to know that the saving money in form of bitcoins is actually good  and everyone would start using bitcoin wallets
We all know that the Value of bitcoins are like waves ,they go real high and then can fall also
People would start saving money in bitcoins and then withdraw them or use them when the value is low
And when all this would become a problem then the Value of bitcoins would become stable in order to make things right

Banks will never disappear, all transactions are heavily dependent from the bank, with the bank all things can be supervised and controlled. I'm sure even though use of the bitcoin great but will not make banks disappear.

Yes it will never disappear because a lot of people always need the services of the bank because they are not just for deposit and withdrawal.

They also do offer guides and tips for investments and they have thousands of professionals that are ready to serve us.

Although bitcoin is a good method if those professionals will apply it with bitcoin.

Yes bank will likely adapt and accept bitcoin once it became mainstream like fiat.

Exactly, they will adopt to the needs of its customers. Bank owners are not fool to just shut down their business because there is a great competition, but rather,they would make their service better and adopt new technology so they could survive. Lets not forget that banks play important role in the economy. They won't be staying that long if they do not do things that could make them better. 

A lot of differences between bitcoin and banks. Just like bitcoin, bitcoins also have the same thing like banks, Banks have the account, and bitcoin have a wallet address, for their differences, bitcoin has a wallet address, but the banks have the account number. In banks, you can loan a big money, without any risks, while in bitcoins, a lot of scammer in bitcoins. A lot of negative effects for bitcoin, but, there is also a vice versa for that.

Yeah, Its like saying if there's digital money, will banks still run? Of course banks will still run without a problem. If bitcoins really grows and is adapted by the society at large. Then we might see some banks adopting bitcoins into their system.
