Why is the kotlin language not popular now?

Kotlin No fire , In fact, it has been developing slowly , It's getting hotter and hotter .

There is no such thing as the original fire is very hot but now it is not .

and google The official emphasizes that all activities are Kotlin first .

Some libraries even support only kotlin. Oh , If you don't care 「 It is specially made for the old version of Hongmeng 」 In a better environment , So the new version of Hongmeng is also everything kotlin Priority .

Maybe the reason why it can't fire is jetbrains It's no match for sun Follow oracle Wait until the company is rich and powerful . Yes , It is not google in order to android The language of creation . It is jetbrains Created to make programmers more comfortable with programming ,google I just chose it .

jetbrains In fact, in the programming industry, the reviews are very good ,jb The family barrel is considered to be 「 The only challenge visual studio Universe first ide status 」 Products . So actually jb Our products should be reliable .

But as far as I'm concerned , Not used before kotlin The reason is still because prejudice . I used to refuse to accept it because of prejudice kotlin,「 since Java That's enough. , Why do you need another language ？」. But I really use kotlin After writing a project, I began to regret ： Regret touching it too late .

quite a lot java The programmer , Especially server-side programmers . Never tried kotlin, So I resisted it subjectively . I understand this 「 Not willing to jump out of the comfort zone 」 Ideas . But soon , The pleasure of new language features will overcome this hesitation .

Theoretically , All available java Virtual machines can be used anywhere kotlin, But actually , part ide It may not be easy to deploy kotlin Editing and compiling , Maybe this will be a hindrance . Who is right ？
