I like Angular and I think it's still a solid choice for new apps in an enterprise setting, and signals are a welcome addition that solve real problems, but I don't understand the hype. Signals are as old as JavaScript if not older. The diamond problem and sync propagation are not new problems. We've come full circle. Old problems become new problems but with the same solutions. What did we gain with all of these iterations if we landed back on what was essentially the Knockout model of 2010?

I'm reminded of papers such as "Deprecating the Observer Pattern (2010) [1]" which documented solutions to these problems a long time ago.
