And during these 25 years you have made it actually difficult (!) to
leverage the power of multitasking. The fact that I cannot have
concurrent tasks operating in read-only mode on the shared container
is a fatal mistake. This is something even C++ can do, which
ironically does not even officially support threads.

Unfortunately, it's not the Ada people that can do this. The game is
driven by CPU vendors themselves, because it is them who show
directions.

One of such directions is this:

I very much appreciate the experience that the Ada community gathered
in the area of multitasking in the context of RT systems, but this is
not enough to gain significant visibility in the multicore game. It
just seems to be a different business and one of the places where this
divergence is clearly visible is that after these 25 years you still
miss the lock-free-algorithms boat.

In short: multicore is about performance, not about Ravenscar.
