Overall progress is not 80%, by any meaningful metric. I mean sure, if we take the 'people who like python 3 and eat burgers but only use python 2 while drinking lemonade sampled from a group of 20 people down at the pub', I guess maybe we're at 80%, but now you're just inventing random statistics for no reason. The only relevant statistic is people actually using python3, and that number is not 80% (and not even close).
