In other words, the “feature” those languages have is reducing the cognitive complexity and more tightly bounding the risk.
Newer languages are adding friction or dropping altogether things that you rarely or never want to do, to more tightly constrain the space of possible actions to the set of desired actions.
so experienced cc devs dont need it and the dream is mostly about creating experienced devs who write fast software damage limited by the guardrails of the environment? so its basically the c#\java world of cheap oo software crawling over moores plateau hopping for one more silver bullet that will fix lowcost development,trying to solve the expensive quality dev shortage once more by cheapening out.
