Serviceability by owner is less and less important as fewer and fewer owners actually do maintenance themselves, though.

Even if 100% of owners choose to pay someone else to do it, they are still benefiting from the user-serviceable standard.

First, anything serviceable by the owner is also accessible to a local garage or independent repair shop. That means a competitive market for those owners, rather that being stuck paying extra to a local monopoly or to a rent-seeking manufacturer.

Second, it makes long-term repairability of the product much easier, things don't just suddenly become irreparable because the manufacturer closed down their "unlock codes for trusted affiliates" site. Their asset retains more of its value.

There are things which provide value even when nobody uses them.

Option 1: "I am so much smarter than these stupid engineers"

Option 2: "Certainly, I do not understand the various trade offs that led to this design"

I wished at least in software tech circles there would be more of option 2 kind of thinking.

I've been not betting on x86 in the long term since the PowerPC was announced ;)

It's sad to admit, but being a chef étoilé does not make it easier to find a job in the fast food industry. It can even be detrimental.

The confusion comes from the fact that the regime which is very clearly better for its own people is also the one which actions are clearly awful for the rest of the world (if only because it has vastly larger means).

So one side is evil while the other side is just wrong ?

Like after 300k deaths in Irak when the administration said "sorry we have been misled by wrong information about the WMD"? They made a mistake, yet Iraqis were evil.

There is serious as in "corporate-serious" and serious as in "engineer-serious".

I’ve seen more 5k+-core fleets running Ubuntu in prod than not, in my career. Industries include healthcare, US government, US government contractor, marketing, finance.

In other words, those industries that used to run windows before ?

I'd say about 2/3 of the places I've worked started on Linux without a Windows precedent other than workstations. I can't speak for the experience of the founding staff, though; they might have preferred Ubuntu due to Windows experience--if so, I'm curious as to why/what those have to do with each other.

That said, Ubuntu in large production fleets isn't too bad. Sure, other distros are better, but Ubuntu's perfectly serviceable in that role. It needs talented SRE staff making sure automation, release engineering, monitoring, and de/provisioning behave well, but that's true of any you-run-the-underlying-VM large cloud deployment.

The analogy with human brains suggests that it would not end very well.

Most importantly, people need to understand how indication leads to verification.
