We’re past the halfway point of Bernhardt’s 2035 timeline; JavaScript hasn’t died yet, but it’s clearly writing its own eulogy in WebAssembly.
* With the one exception of BLAS which is widely used via NumPy
It's like PHP, it will never die.
I predict that PHP will live a long life, but not as long as C, and I predict JavaScript will have a lifespan closer to C's than PHP's.
