> His final argument is then, since the borrow checker doesn't provide "entity safety", it impedes on games development because Blow (and any other modern game developer) would have been smart enough to start with a proper ECS system anyways and the borrow checker wouldn't have bought him anything.
But even in C++ gamedev using a proper ECS, one is still using plenty of plain-old references all over the place for things unrelated to the world state, no? If so, then saying "the borrow checker doesn't help manage world state" doesn't imply that the borrow checker doesn't benefit the codebase in other places, especially considering that use of an ECS circumvents the places where we have determined that references (and hence the borrow checker) are already poorly suited to model.
