The only (arguably*) baseless claim in that quote is this part:

it’s theoretically possible to write memory-safe C++

Maybe try to write more humbly and less fanatically, since you don't seem to be that knowledgable about anything (experienced in other threads too).

* It's "theoretically possible" to write memory-safe assembly if we bend contextual meanings enough.

The only (arguably*) baseless claim in that quote is this part:

You do understand you're making that claim on the post discussing the proposal of Safe C++ ?

And to underline the absurdity of your claim, would you argue that it's impossible to write a"hello, world" program in C++ that's not memory-safe? From that point onward, what would it take to make it violate any memory constraints? Are those things avoidable? Think about it for a second before saying nonsense about impossibilities.

  • C++ offers no guaranteed memory safety.
  • A fictional safe C++ that would inevitably break backwards compatibility might as well be called Noel++, because it's not the same language anymore.
  • If that proposal ever gets implemented (it won't), neither the promise of guaranteed memory safety will hold up, nor any big C++ project will adopt it. Big projects don't adopt the (rollingly defined) so-called modern C++ already, and that is something that is a part of the language proper, standardized, and available via multiple implementations.

would you argue that it’s impossible to write a"hello, world" program in C++

bent as expected

This proposal is just a part of a damage control campaign. No (supposedly doable) implementation will ever see the light of day. Ping me when this is proven wrong.
