Here is ChatGPT’s take on Julia type inference:
Type inference in Julia is related to, but not exactly the same as, duck typing.
Duck typing is a programming concept that says "if it walks like a duck and quacks like a duck, then it must be a duck". In other words, if an object has the necessary properties and methods to behave like a particular type, then it can be treated as that type, regardless of its actual type.
Type inference in Julia, on the other hand, is the process by which the Julia compiler infers the types of variables and expressions at compile time, based on the types of the values being assigned or used in those expressions. This allows Julia to generate efficient machine code that takes advantage of the specific types being used, without the need for explicit type annotations in most cases.
So, while Julia does use some elements of duck typing, such as the ability to treat objects as different types based on their behavior, type inference in Julia is a more specific process that is used to optimize code based on the specific types being used, rather than just allowing objects to be treated as different types based on their behavior.
