I don't think that it will ever happen as the internet is improving day by day and in future we will see internet with some great features and higher speed so there is only a room for improvement from here and it will never go back and it will never become dead.
Yes, but the problem that we discuss in this thread has not a lot in common with the things you are talking about.
Higher speed of the internet and better features in it does not help it when something unexpected happens, which may cause internet to go down on the whole planet.
The infrastructure needs to be modernized, because without proper security measures and safety plans, in the event of war there might really bad things happen for bitcoin, as a cryptocurrency.
But to be honest, I think that it may only affect BTC in case of a really big war, which may become a national conflict.
I think that with the stable internet, most of the cryptocurrencies are safe unless people lose trust to them for some reason.
I think what he meant by "internet is improving day by day and will have great features" in the future is that as the internet becomes more stable and secured. Meaning, having such features and improvements, it will be totally impossible that such a phenomenon will occur. Also we are now getting more and more modernized, so we will be so dependent to internet because the technology that we are inventing always uses internet.
