Not anytime soon, even for 5-10 years imho. Central banks control monetary policies and controlling the nation's entire money supply, which mean the bank will stay around for decades or centuries as long as the country has an official currency. On the other hand, bitcoin is a decentralized monetary system, but it can work perfectly fine as a medium of exchange just like fiat currency. Probably banks will become obsolete if a country no longer has an official currency, in Zimbabwe and Venezuela where inflation goes crazy and their currencies worth almost nothing, banks still exist though.
