What do you think? Will "De-Fi" beat banks in the long term? Or is it still too early to tell? Do banks consider "De-Fi" as a threat to their existence? Your input will be greatly appreciated. Thanks in advance. 
No even we count for decades. The banking system is so huge and will evolve more while in progress. Big individuals, business owners, big people, downed to a regular person will still prefer a centralized system because of safety, assurance, and being insured in case of a fu*ked up.
But honestly, I want to see a full decentralized system but already accept the reality that it won't happen even by less chance.
Rather than replacing banks, why not hope that they will exist at the same time, take advantage of them and enjoy both.
