I went through the whole, “What if an EMP” happens.
It is much more likely that an EMP would be a local, not national event. And that means that the internet would not be dead, just knocked out for a while.
Even more likely is a CME, which would blast the who day side of the planet. Again, money in that situation would practically worthless.
Finally, the more I read about EMPs, the less I worry about them. There is a wide range of scholarly work out there. They range from the “its the end of the world” to “Your car will stop, and then start up again—unless it is right over your head.”
So, based on those things...I think its OK to think about future technology. :-)
We are living in perilous times, IMO. Now is not the time to allow the pantry to get low. As for assets, have as many different assets as possible, including cyrptocurrency. :)
