Not a mainstream view.
Python 3 is a hugely successful language and implementation, and almost no one regrets that it exists aside from a few noisy holdouts, and people who never liked any Python anywhere at any time.

The Python ecosystem has been growing overall especially because of the success of things like Pandas, but a lot of backend/fullstack web app programming did move away from it and never looked back.
(Though you might say the more interesting question is: would they have moved away to things like Node for async/perf or JVM-stuff for "maintainability of old large codebase with lots of devs" issues? Maybe? But at this point Python has added in a lot of things from those languages; but maybe if they'd been there five years earlier with a cleaner upgrade story the migrations wouldn't have happened.)
That lead to a chicken and egg situation: if you depended on those libraries that did not migrate to python3 you where stuck at python 2 as well.
I believe being nice to the community and supporting python 2 for a long time was a mistake. They should have made a hard break and enforce the migration...
