Of the three options you presented as being potential results of putting forward arguments supporting my dislike of Rust, the third is interesting. I am quite sure that a vast majority of actual Rust programmers would consider addressing my concerns to be an active degradation of the language. Somewhat related is that I'm not particularly concerned with people (particularly Rust users) agreeing with me, nor do I think that would be a plausible result. So, that leaves the potential for being shown information that would "address [my] concern" as a potential result. So...

I have relatively strong opinions about quite a few areas that Rust, as a language and accompanying programming & tooling philosophy touch on, so I'll just do a few as examples:

1) I am strongly adverse to package managers (I didn't pick this example to get a rise out of you in particular) and their usage by programming languages. I am hostile toward the trend toward more and more dependencies in a given executable, which is only made worse by the industry adoption of languages that support and promote the "find a crate/get from NPM" attitude toward incorporation of dependencies. I don't know if there is evidence of a exponential explosion of transitive dependency in languages relying and building on a package manager ecosystem, but I wouldn't be surprised if it worked toward that point. I know that one does not have to use Cargo and the crate ecosystem, but it is a huge point of pride for the community and is THE idiomatic way to handle dependencies in Rust.

2) I have strong philosophical disagreements with ad-hoc polymorphism in general and with Rust's choice of pervasive reliance on its trait system all through the standard library and all examples of idiomatic code. At this point in development I don't even think there is a means to remove the ad-hoc polymorphism from Rust's implementation as a language. This point in particular I can not see any active Rust user being seen as an improvement of the language. Further, and although Rust does not have a definition of the language or a formalization of the type theory used by the language, I can not see a world where Rust adopts Haskell's position on the typeclass system being a convenient syntax sugar for a non-primitive and more explicit semantic form.

3) I am both practically and philosophically opposed to the usage/presence of 'ownership semantics' as a core part of the semantics of a programming language. Note, that I don't oppose the encoding of the commonly used meaning of 'ownership' at the type level via expressive types, as it can be an accurate description of the relationship between various data in a program. I do object to 'ownership' being the foundational semantic understanding of all programs and data used therein. There is a chance that Rust could incorporate a sophisticated type theory in a future release that relegates the current imposition of universal ownership semantics into a constrained area and allows for alternative semantics to be used in appropriate places, but I think it is nearly impossible to do and maintain validity for any prior programs.

So, do any of those three example look particularly appealing? I know you, only by reputation and seeing previous comments on HN, and know you are fairly involved in the development of Rust from several directions. Can you see Rust becoming a language with very limited ad-hoc polymorphism, a strong break away from the ownership semantics used today, and a language that does not place a package manager in a place of importance for idiomatic development?

Of those three examples the only one I can see anything being said that would alleviate my dislike is to just not use Cargo and build everything from scratch or find and download tarballs, which I would probably do and not complain if I had to use Rust. Thanks for your response being not particularly aggressive, I appreciate any time you gave to read this wall of text.
