This is a wonderful roundup from Jeremy, who I picture circling January 1, 2022, in red marker on a giant paper calendar back in 2008 and patiently counting the days.
See, there was a little smattering of internet drama back in 2008 (weird, right?) where Hixie kind of “officially speculated” that HTML5 would take 19 years to make it to full “recommended” status (2003-2022). Seems like most web developers at the time were quite certain HTML, and perhaps the internet as we know it, would be essentially obsolete by 2022. They were not right.
