Remarkable the faith people still have in fiat, given the mathematical reality.
All $USD has to do to become obsolete via being inflated away into nothingness, is continue what is has been doing since 1913.
All #Bitcoin has to do to become the next global reserve currency is continue what it has been doing since the 2009 genesis block. 
People are learning I can tell
Faith yes, but downstream from that is 1. Many people simply don't understand economics and therefore how bad our current circumstances are, and 2. Fiat is still what everything is denominated in. Bitcoin still early enough that most people don't see how it can be more than an investment/savings vehicle.
I agree with both of these points. I also want to add that worries about tax code, data loss, incurred fees and just having to learn a whole new way to transact are also barriers.
Data loss?
Data loss, like through lost keys, or lost hard drive. I also wonder about resiliency in an EMP or grid down situation. I assume I can’t be the only one that has these questions.
Ah I see. Much can be said on this but here are a few shotgun responses:
1. Lost keys=yes. Self-custody requires a lot of responsibility. There are a number of custody solutions depending on each person's risk tolerance and more options/solutions will likely continue to emerge.
2. You can keep your keys on a hard drive, theoretically, but if that's you're only backup it isn't the smartest option. Other than that a hard drive shouldn't need to factor in.
3. Bitcoin, nostr, Tor, and other distributed networks are the most resilient on the planet. No single point of attack or failure. Grid goes down due to emp, solar flare, cyber attacks, etc. and distributed networks are likeliest to survive because such events are typically not global and even if there were a global scenario, it is unlikely that the effects would be exactly the same everywhere. Meaning, while certain areas are down, other areas might be back up, etc. Beyond that, if a situation were catastrophic enough that all grids and all digital networks were down everywhere on the globe all at once and to the same degree for any period of time, we would have much bigger issues than *oh no bitcoin is down*. Even then, theoretically, if things get back up and running *anywhere* and there are any nodes and miners there, the bitcoin network may be the thing that's the most likely to come back online relatively unscathed. But such a scenario has not been tested (obviously and thankfully).
