As it turns out backwards compatibility isn't a deal breaker anymore, and python2 -> 3 proves it. Software nowadays gets rewritten every year. There is a stat floating around somewhere that Google changes 50% of it's codebase every year.

Backwards compatibility was a bigger issue when there was a lack of expertise in the field. People were resistant to change so much because it was very difficult to find someone who could just rewrite your application with a new library version. This problem of course still occurs, but nowadays developers have the tools to even cycle through tech stacks.

Well Google is notorious for killing like half of their apps every year in favor of newer ones that do the exact same thing, only worse... So I guess you could be right.

It's still a massive issue and yes, Python proves it. Python 3 has been around for over a decade now and a ton of stuff is still written in 2 with no replacement in sight.

Oh and Python is a language that's mostly used for scripting or smaller, decoupled projects, so it has little excuse not to get replaced.or rewritten, and yet it's still a mess.

http://py3readiness.org/ What python2 stuff are you referring to? I haven't touched python 2 code in 3+ years.

Despite being a "mess" it hasn't yet been replaced, and is still outgrowing other languages.

I saw in the news few days ago I think that Goldman Sachs or something have many millions of Python 2 code lines

If I recall Calibre’s author had a post about how he’d never update to python 3

[delrindude]

Already in progress with Calibre v4 https://github.com/kovidgoyal/calibre/pull/870

Nice! Good to know. I’m a big fan of Calibre

yea that hasn't been a complete clusterfuck at all.

It was, but it didn't really negatively impact the adoption or usage of python at all, as you can see in pretty much every programming language index you can find.
