The web really needs native templating, reactivity, and data binding.

I can't even begin to imagine how much CPU and bandwidth is wasted with billions of users downloading, parsing, and executing something like React.

With the TC39 signals proposal, part of that is making progress.

if (when?) Signals become a standard, React will be in a tight corner if they decide to ignore them

Not really? `useSignal` is just another hook React needs as a replacement/augment for `useState` and maybe `useEffect`. Signals aren't that special. Arguably that's part of why a lot of people like Signals as a proposal.

(I'm still of the sort that thinks Signals are just worse Observables, so it's not a proposal I'm particularly thrilled about, but were it to be adopted Signals are easy to use in Observable contexts as well, they are just uglier half-implemented BehaviorSubjects, though maybe with a few extra lint rules to prefer Observable behaviors over Signal ones.)
