> I struggle to understand the mind set of people who do not want to use them

It usually comes from people who never had experience with statically typed languages, don't work on projects with a large dev team, cross teams projects or work with a lot of 3rd party libraries. They don't realize the maintenance nightmare that types can easy.

Sure you write one off script, or something that is rarely run don't use types, but when you have a 50k lines codebase that is actively developed and maintained it's another story.

I'm so glad Typescript changed that mindset of frontend developers and is supported by a lot of prominent open source projects

That might be where it usually comes from, but that hasn't been my experience. My Python subcommunity groupthink was against type annotations for years, despite the groupthink also saying that statically typed are better all things equal and most of the loudest folks having worked for some FAANG company.

Thinking that typing is good and buying that a pasted-on-after-the-fact typing system is good are different matters.

In my experience, it was quite jarring to see a python function with a bunch of : -> Union[int,str], Optional, Any, etc.

Change is always hard.

I actually don't understand Optional in that mix. "Optional" basically means the value can be "None". You typically use it like this "Optional[str]" which means the value is a string or "None".

Very true, but there is a gradient there. I have an example of the opposite extreme. A few years ago I worked with a person who would rather continue working in php 5.3 than start using Scala, which was hot at the time. He literally copy-pasted an old project instead of starting a new one in Scala (or ANY other language, this was a payment system and php does not even have strong enough crypto support in old versions). And I can tell you for sure he had at least 1 year exposure to Scala and doing at least 1 full project. His reasoning for copy-pasting old php: He was «just too stupid to understand Scala». It is an extreme example, but most people I met who dont like strong typing fall into that category (lazy? Certainly not stupid) and I just dont know what to say to them or what to think myself to accept them or even how to use whatever hidden powers these people have other than creating circular dependencies for the company by making obvoius mistakes they themselves spend most of their time fixing. Im not actually bitter, just frustrated that so many seem to just not care.
