Having talked to people who were in charge of making some strategic decisions regarding a business messaging application...
Slack/Discord is "too complex and confusing". Apparently the pile of unsorted chats, group chats, and meeting chats, are superior to Discord's threading model.
Also corpos literally do not notice that teams is slow as molasses which is a big part of the friction. You could show them a perfect demonstration that Teams' UI is so much slower to react to anything (nevermind load the actual resource) than the competition and that they often have a 1000+ms audio RTT in meetings (not a hyperbole) and the business people would be like "yeah, I guess? Who cares?"
Corporate types literally can't understand that bad audio and audio latency costs a huge percentage of revenue in lost productivity because everyone's constantly talking over each other and simultaneously being too afraid to speak because the audio delay makes it impossible to fit into a lull in the conversation and also everyone is in a competition for the tiniest shittiest mic with the worst noise canceling that somehow stacks on top of Teams' pretty bad noise cancelation such that their voice is being noise canceled and you're just left with like 1.2 kHz of actual range and somehow everyone seems fine to spend their entire day listening to that and aaaaaaaaa I have a headache and I want to die
Then after work you get on a discord call with the mates and everyone is crystal clear with no noticeable latency, even the students on a secondhand 30 € gaming headset.
I despise crypto, crypto-bros, and do not own a single unit of cryptocurrency. Crypto is not only impractical due to its fluidity but almost every crypto is deflationary by design which disincentivizes people from spending it.
With that out of the way, the blockchain is certainly more resilient to a "fuck you" class solar flare than the regular economy. There are for sure a bunch of people with EMP-resistant copies of the blockchain (since every node has a copy). As soon as internet goes back up, so will the crypto-bros.
Meanwhile cash makes up only a few percent of fiat currency and the rest is digital money in databases around the world's banks and financial institutions. Almost all cash flow is completely virtual and literally cancels out in accounting at the end of the day.If those databases get wiped, the global economy simply collapses and your paper money won't be worth shit-fuck. Admittedly neither will crypto since no-one actually uses it for anything other than exchanging it for fiat.
One of crypto's major problems is that it actually behaves too much like cash. Every bitcoin is a non-fungible token, it's not tied to gold but might as well be; exchanging a bitcoin costs exorbitant amounts of crypto and real-world resources. Meanwhile if my bank wants to give me a big loan they merely change a number in their database. On a technical level they could give me a one trillion euro loan today if they wanted, although that would run afoul of many laws and immediately bankrupt them once I tried to actually spend that money in what would quickly turn out to be a one-man bank run.
