Developing a new Web browser is by now an endevour comparable to the Apollo missions - and probably even more complex.

There are 1191 W3C specifications and recommendations out there right now (actually a bit less than the time when that article was written in 2020).

That’s about ~110M words.

Put togeter the C11, C++17, UEFI, USB 3.2, and POSIX specifications, all 9580 published RFCs, and the combined word counts of the 10 longest novels, and you still won’t reach that many words.

Even building a fully POSIX-compliant operating system is by now 1-2 orders of magnitude less demanding than building a fully W3C-compliant #browser.

I guess that’s probably why both #Google and #Mozilla feel free of enshittifying as much as they like and get away with it.
