He's 100% wrong. Use Python 3. Don't spend a second thinking about Python 2. His complaints are bizarre. He mostly claims that Python 3 sucks because he can't figure out how to convert his old Python 2 code to work on Python 3 easily so therefore a beginner couldn't possibly learn the language from scratch. But all of his examples are edge cases of him intentionally fighting against the changes in Python 3 by doing things that don't make any sense like trying to concatenate unicode strings with raw binary data. It's just the weirdest argument ever. Python 3 makes almost everything slightly simpler and more logical - especially if you ever have to deal with unicode text. And since emojis are unicode and people love emojis, that means literally everyone. Overall, he comes off to me like people who spend a lot of time ranting about USB-C ports when in reality USB-C is mostly great and honestly just isn't that big of a deal anyway. It's a strange hill to die on. The only good historic argument for using Python 2 was that it used to be that some popular libraries weren't updated for Python 3 yet. But that hasn't been true for years. Nowadays you are more likely to run into libraries dropping Python 2 support than you are to find them not supporting Python 3. I can't think of a single remotely popular library that still doesn't support Python 3.
