I don't think we should dispense with it for that reason, but we also then have to admit imperative programming doesn't match the design of promised future hardware as well as it has past hardware. The future will be focused around manycore distributed heterogenous compute resources like GPGPU, neural cores, computer vision accelerators, cloud compute resources, etc.
Even languages with 'exotic' execution semantics like prolog's Unification is actually implemented with an imperative interpeter like the Warren Abstract Machine/WAM, and there's not an obvious path to implementing such unorthodox semantics directly in hardware. Low-level imperative programs aren't going away, they're just being isolated into small kernels and we're building higher level abstractions on top of them.
That said I agree that we've barely scratched the surface of the space of good paradigms; I'm partial to logic programming but most are underexplored. Perhaps other approaches can use Rust or its IR (MIR?) as a compilation target. As an example, this strategy is being used by DDlog ( https://github.com/vmware/differential-datalog ).
