I thought there was a name for this(cant find it), but its not just devs, its most people with a deep technical expertise.

I remember watching a youtube video about this, where they used Neil deGrasse Tyson as a case study. Showing cases of him confidently saying wrong things in fields he's not very knowledgeable in.

Ne supra crepidam? "not beyond the shoe"

I think k8s has a learning curve, absolutely, and there are absolutely cases where it can be unnecessary overhead. But I actually think those cases are pretty small. If you're running multiple apps, k8s is valuable. There is initial investment in learning the system, but its v-extensible, flexible, & portable. (Yes, every hyperscaler's implementation of k8s has its own nuance in certain places, but the core concept of k8s translates very well)

We must be terrible at implementation bc we have a had a prod outage and our DX is objectively worse. Its caused more problems and headaches for us.

If you are out of the magnetosphere, wouldn't your data be subject to way more cosmic ray interference, to the point that its actually a consideration?

In LEO, there is a lot of testing and mitigation you can do with your design to help reduce the chance and impact of radiation single events. For example, redundancy for key components, ECC for RAM, supervisor hardware, RAID or other storage tooling, etc.

Geostationary orbiters operate there during the day but this concept would position systems 100x closer to earth and well inside the protective envelope.

ECC everything?

Yes. And most server hardware is already at least ECC ram. You may still want some light radiation shielding to prevent the worst, maybe some heavier shielding for solar flares. But beyond that, simple error correction can be baked into the software - ecc the bootloader and filesystem and you are mostly good to go

Isn't ECC only applied to RAM? Do any current gen CPUs have ECC cache?

I can't comment on AMD or Intel but Apple Silicon definitely uses ECC for at least the system level cache. On top of that it performs cache healing (swapping out bad lines for spares) on every cache level every time the system boots.
