> The change had the unintended consequence of causing IPv4 addresses to start being passed as an IPv4-mapped IPv6-compatible address to our IP Allow List functionality.
My position is that early SRE solved the hard parts, before I was involved. Services and platforms became reliable. The field is mature. SREs still point to risks, but execs have called their bluff.
The takeaway is to make sure you are actually creating value. Maybe Twitter's SREs were not actually improving reliability much.

I think the (well esteemed) author is overestimating the marginal impact of science fiction, and has mistaken correlation for causation.
Humans expanding their habitats is just plain old humanity doing its thing.

2000s: web scalability was an emerging field.
2010s: web scalability was a maturing field.
Scalability feels mature now. Maybe we'll see shifts: CRDTs, global SQL DBs?
I know nothing about rockets but bits of project management: it's common to break down projects into smaller parts and derisk designs/implementations by testing each piece.
The refueling team might be ready to test, even though the "don't explode" team are still working on it.

Sounds like this bug: "Unable to reliably distinguish IPv4-mapped-IPv6 addresses from regular IPv4 addresses" https://github.com/golang/go/issues/37921 .
Use https://pkg.go.dev/net/netip instead.
