I think the often cited problem is that if a national electricity grid goes down, its a very long and complex job to get them back up again, especially if transformers are damaged.

If there's no damage, it doesn't take that long. We had a blackout in 2009 in which the national grid of two countries (Itaipu is shared between Brazil and Paraguay) went down; I'm looking at the official report right now, and it took less than half a day to restore nearly all of the system for this country. Of course, if there's damage beyond the redundancies, it can take much longer; see for instance the recent bla…

2003 had a large blackout across the US and Canada, looks like it took 4 days to restore power everywhere: https://en.wikipedia.org/wiki/Northeast_blackout_of_2003

I’m continually shocked at how little people appreciate just how lucky we were with this recent pandemic.

Yeah can you imagine if it affected young people in the way Spanish flu did? I honestly think we’d be lucky if our civilization didn’t collapse in the face of something like that, given how this version went down.

I'm not a virusologist, but I read that Spansh flu would be beaten pretty quickly with modern knowledge and procedures. COVID's advantage is that it's not that lethal and often asymptomatic.

It only makes sense to have protection if you are going to have enough protection to fend off all 20 million of those zombies.

That is what community is for. I would imagine an armed community would be in a better situation than an unarmed community or unarmed individuals.

I would say that's what the State the ultimate community) is for (police, army but also judges, doctors, laws requiring companies to implement the required safewards, ...), but I'm European, so I guess we simply see the world in very different ways.

Right I think that will happen as well, I am interested in better price discovery instead of arbitrary barter. I will support the cause to build the infrastructure for better price discovery. Transactions can be broadcast to the chain which is supported by an asset with many assurances and confidence about its supply. I don't actually care about the cryptocurrency being a reserve currency or any ideology fantasizing…

I legitimately do not understand what you're getting at. Society collapses, and you believe people will use cryptocurrency for barter instead of tangibles like water, food, ammunition and/or weapons because people will want to optimize the prices? What are you saying?

that they'll use it for easier reference value and an option, yes

if its easier for you, just imagine that its for the monocle wearing investment bankers that still want to offer intangible services and settlement over a network

you are missing that: a) an immediate steep drop in difficult will allow the network to resolve transactions without loads of power, and the few nodes online will still comprise the network. some networks have much longer difficulty adjustment periods and they will be debilitated for months as blocks will not come, other networks have much shorter adjustment periods and will generate new blocks in minutes b) that tra…

It’s delusions like this that lead me to believe cryptocurrency is a cult.

Odd take. I'm talking about a technological option for settlement that will simply exist, not an imagination of ubiquitous use.

I feel like you and I have wildly different expectations of societal collapse scenarios.

Yes our assumptions are different but the key thing to realize is that certain concepts simply wont go away

Radio can be recreated easily, and so can the concept of two computers talking to each other

Cryptocurrency does not need ubiquitous internet

The nightmare scenario is a follows; You get a really large solar storm and no one notices it, so all of the high voltage grid transformers are connected to the grid. The currents induced by the grid burn out these transformers and they have to be replaced before power can flow again. But these are very large, long lead time items that we don’t leave just laying around. And now you need hundreds of them, but the supp…

I would like to submit Texas' recent near grid collapse due to cold weather as exhibit A to prove that knowing about a potential problem for over a decade does not mean that a bunch of disparate private entities will do their due diligence to prevent disaster.

The grid collapsed? Then how on earth are people using power?

Oh you mean energy suppliers off-lined production temporarily and most resumed operation once the storm was over.

Totally the same phenomena.

It can be avoided if we will start to protect our electronics and networks right now. At least most critical ones. The protection technology is available already, just need to be integrated everywhere.

Hurry up and replace all our satellites!
