Yes in that example you already have entanglement/decoherence in (2), at which point I’ve already said the multiple worlds must now exist. Sean’s language in that very article uses terms like ‘we expect the apparatus to become quickly entangled’ and ‘once our quantum superposition involves macroscopic systems’ and ‘proceed to evolve’ and ‘it is as if they have become distinct worlds’. They ‘come in to being’. They ‘occur’. All of the terminology implies the actions are happening over time.

Saying the possibility for all of the worlds is always there is not the same as saying all the worlds are always there. If that’s what is meant, the language should be clearer. Which I will find out.

And yes you were trying to explain ‘apparent collapse’ but you didn’t use that terminology, like the terminology Sean does in the article linked, you just described collapse multiple times, which isn’t happening. I was just pointing out that it’s not ideal and already stated what I assumed you meant, which is exactly what you apparently meant, but you are again doing the thing where you default to telling me I’m wrong when you actually completely agree with me but have an inability to accept your own fault. Kinda tiring tbh.

Edit: It just occurred to me that you said my objection is that there are too many universes. I didn’t realise you still don’t understand my point this far in 😩
