If you operate a train and decide to equip it with WiFi, but the train goes through tunnels every few minutes that completely kill the internet connection, you would have been better off not installing WiFi in the first place.

An interesting trend I've noticed in recent years in FIRE forums is an increasing number of people who include cryptocurrency in their portfolio breakdown.
Prior to 2020 this would get you laughed out of the room...

It's not a "claim," it's a fact that anyone can verify by reading the whitepaper or by inspecting the code.

It's probably true that most people are overly concerned with other people's opinion of them.
Thankfully I've never been constrained by those social norms. I've always been the weird one who does I find interesting rather than what others approve of. It's the mindset that brought me to Bitcoin and it has served me well.

Gmax from the top rope:
"I deeply regret ever making [Luke-jr] bip editor when I couldn't continue doing it. Because the the job was supposed to be non-editorial and purely procedural something of a human rubber stamp I hoped it would give him an opportunity to develop his interpersonal skills in an context where his narrow-minded focus wouldn't be a hindrance and where a wonkish approach could even be a bit of an asset. This turned out to be a disaster because rather than following the limited requirements of the process he has systematically distorted reality so that he could falsely declare things to be violations of the limited requirements in order to get his way. It was a real error in judgement on my part although it's one that is overshadowed by the error of the current project leaders in failing to end Luke's abusive influence even after he started explicitly calling for the destruction of the project."

Sadly, I can no longer recommend Gandi for hosting services, as their support quality has tanked since they were acquired a few years ago.
I used to be able to get a response within an hour or two if my server went unresponsive. My latest issue, which was a kernel problem I consider to be Gandi's fault for changing how their virtual machine hypervisor works, saw my support request hanging for 4 days before they sent a generic "this is your problem, we can recommend some third party consultants to pay if you want."
Thankfully I hadn't sat around waiting for them and managed to resolve it myself in an hour with the support of an LLM.

Absolutely. It's impossible to create a protocol that is absolutely impossible to change: the best you can do is to align incentives that make certain aspects unlikely to gain sufficient consensus to coordinate a change.
With regard to changes in the absolute / effective money supply, the only way one could imagine gathering consensus to change them is if it's done to avoid some sort of catastrophe.

Thus it's a fascinating conundrum.
The rules are ultimately what people want them to be.
The flip side of "you can't confiscate coins" is "anyone can choose to reject coins with certain characteristics."
There are countless cases of protocols upgrading their security over time and users of those protocols rejecting interactions with other users who refused to upgrade their security.
