One of them is Julia! - https://github.com/JuliaPy/PyCall.jl .
The other is Swift - https://github.com/tensorflow/swift/blob/master/docs/PythonI... .
And here is the kicker: Packages is Julia are far more interoperable than in any other eco system I have seen.
Than means 10 packages in Julia can quickly do more than 50 packages in other language. Say somebody makes a GPU processing package and somebody else makes a Machine learning package. They don't know about it each other.
Yet with Julia we frequently see that these guy can use each others package. The ML package can with little effort run on a GPU by including a GPU package even if it was never designed for it.
Julia just moves way faster than the competition and that is why Julia is NOT doomed.
That's because Python already has tons, while Julia lacks tons.
Are the new ones added to Julia as good or better though?

This sounds like magic bullet / handwaving.
Perhaps Julia's multiple dispatch helps here (?), but why would the above be the case and wouldn't be achievable in other existing languages as is?
It's not handwaving when it already exists. CUDAnative.jl gives native compilation of Julia code to GPUs, which allows CuArrays.jl to do efficient loop fusion among other tricks. This is then enough for DifferentialEquations.jl, Flux.jl (the big neural net library, think PyTorch), CLIMA (a MIT-CalTech next-gen climate model), etc. (too many packages to list) to all utilize the same underlying GPU framework. It's as if someone got rid of the GPU functionality of Numba, PyTorch, TensorFlow, etc. and just made one good enough Python library for everyone to share. As you can imagine, that reduces the amount of work to do package development but gets the same functionality in the end with a lot less maintenance issues. You can also say the same for how many JITs and transpilers to C there are in Python libraries vs the single Julia JIT.
The real danger of the Python monoliths is that when something as simple as a neural network package starts to include a JIT, a GPU compiler, and automatic differentiation library, and it's all written in C++, it gets really hard to attract developers because the code base is so hard to understand. This means that instead of getting new developers and more maintenance, people just spawn new libraries all of the time in Python, starting from scratch to write a new JIT, new GPU kernels, etc. I just cannot see how that's a good thing.
Yes, ubiquitous, zero-overhead multiple dispatch is the reason, as explained in depth here:

Maybe you guys would like to compare your text editors now?
F#, obviously.
Modern is not some "PL-community favorite with small following" a la Haskell, it's what programmers in the trenches are using. The same way a modern car is (pick a popular current model) and not some limited edition car with limited sales.
C# "keeps up with the Joneses", brings in ideas from functional programming (bringing in F# features incrementally), etc.
LINQ, pattern matching, dynamic, value types, tuples, destructuring, async/await, null-coalescing operators/assignment, streams, and much more...
Not only is up there with any popular language in the same domain (Swift, Kotlin, etc), and way ahead of Java, but compared to something like Go that gets people excited this is space technology.
(Plus is not like multiple dispatch is a new development, or gradual/optional typing is the "new" thing - we had those things for decades, and I don't see them catching on except the latter where necessary - e.g. adding gradual typing in JS/Python/etc variants like TS, where they can't have strict static typing for compatibility/historical reasons. The only language with gradual typing I remember in recent times was not very cutting-edge itself, Dart, and didn't manage to go anywhere).
What do you mean by memory hopping, reference types? C# has had value types since the beginning unlike Java.

Library ecosystems have a human workforce value of billions of dollars, available for free. Any modern language that want to go mainstream must offer transparent and complete interoperability with an existing ecosystem. TypeScript -> js Kotlin -> jvm C++ -> C Elixir -> Erlang Hack -> php Crystal -> ruby
As we can see there are still Big ecosystems lacking a new modern language™ The python ecosystem The C# (CLR) ecosystem
It could be said that's mainly because those languages are already mostly "modern"
There are also dying big ecosystem and there would be economic value to make their old libraries accessible. Fortran Pascal Perl Etc
