It took 130 years to become widely adopted and few years later there are e-mail that beats the existence of these fax machines. Some offices may still use this however the existence of e-mail is undeniable and much more efficient. On the other hand , the same thing could be applied to BTC as there could be some potential technology in the future that might replace it .Closely looking, some altcoin actually got the potential to beat BTC or atleast on par with it in the future.
You probably never worked in an office but i can tell you that we still use fax machines quite often actually, although emails may be better fax machines are somewhat more reliable and when you send something they give you a confirmation paper as well.
I could see that you probably dont even understand whats my point is as I dont actually interested that if an office is still using fax machines or not. Offices may still be using it but sooner or later fax machines will be a history.
My point will be that I am stating once there is another new technology then the old one will be left over as people are much more interested with new things instead. Also another main post of my statement is to mock the issue about increasing block sizes as the tendency to stay "the same" without any concern for the future could actually almost be like to make BTC dead
