GC is a means not an ends and we shouldn't be attached to it. We should focus on developing languages that allow the compiler to statically assess and infer lifetimes then we don't need a giant for loop over all of active memory. The value GC provides is it gives the developer an escape-rope from an insufficiently expressive language. If that solution involves some form of GC so be it, but the goal should not be to preserve GC but rather to improve the efficiency of the final product without substantially impacting developer ergonomics.
So far that sufficiently expressive language, usable by mainstream developers is yet to be invented, and no Rust isn't yet it, too many hurdles to overcome in common programming patterns.
