Google itself has moved on from Angular. They invented Lit, the anti-framework, which has far less scaffolding and cruft and is based on browser standards.
Google is a very big company. They have maintained polymer(now reincarnated as lit), angular and angular dart. No reason to believe that there will be a change in status quo
Not sure I follow this? Lit seems to be hanging on by it's fingertips? It's official starter's dependencies is (was very recently)? painfully outdated. Angular continues to evolve with what seems to be many more people working on it and a budget.
