The problem is really that Python 3 isn&#x27;t new and shiny. It&#x27;s an attempt to improve some downsides of Python 2 and some parts did actually get better but many parts didn&#x27;t although they easily could have been improved, some parts even got worse.<p>Python 3 provides no real benefit to an experienced Python developer. So considering all the things you could possibly do, switching to Python 3 is not switchting to a new and shiny thing, it&#x27;s just a bad decision.<p>If you really want to switch to something new and shiny, there are now many more interesting language options. Modern Javascript has copied so much from Python, you can feel very much at home there. If you care about concurrency, you have Go. If you care about concurrency and care about using a language that&#x27;s well designed or just want performance, there is Rust.
