I'll say something on the subject too, because I helped derail the topic a little. The reason why I think it's hard to vote is that physicalism and a matter of "information" are both conceptualizations, but reality isn't really made of anything specific.QuantumT wrote: ↑Fri May 25, 2018 8:14 pm Are we currently witnessing science being divided in two directions?
In the one: Old school physicists, who insists on physicalism/materialism, and the traditional approach that derives from Newton, Darwin and Einstein.
In the other: a more modern information approach, deriving from Bohr, Heisenberg and Schrödinger.
I have noticed the first group mocking the latter alot. Especially among amateur scientists.
The real ones just say: Shut up and calculate. They seem to avoid interpreting "the wave collapse" at any cost.
If they don't avoid it, they find speculative explanations that confuse the audience so much, that they forget the essence of the issue itself.
Is the information approach a fad, a new branch or the future of science?
"Information" is a dimensionless concept invented in the 20th century. It can also be used as a super flexible catch-all description, abstraction of physical systems. Matter/energy/material/physical is a more diverse and less flexible and much older description, abstraction of reality.
It doesn't really matter which one scientists use as long as they don't mix the two like Susskind does with black holes. Percieving reality twice and then saying that it's really made of two realms is just magical thinking. But I think there is indeed a trend towards the information-conceptualization because it's so flexible. I too find that it's pretty much only possible to think about QM in terms of information.
You misunderstand the deal with wavefunction collapse. Certain interpretations say something like: quantum superpositions are pure information or information waves or there's some universal bookkeeping device or whatever. Other interpretations say different things, like those superpositions don't "exist" at all, or there are hidden variables like guiding waves (ewww), or it's all just "potential" all the way down, or that the wavefunction is physically real and so we see a slice of a reality that extends sideways multiversally (MWI-type).
There are dozens and dozens of interpretations, people have literally come up with everything they could think of to tackle the wavefunction collapse. But in an age where they can put objects big enough to be visible with the naked eye into two states at once, it's getting harder and harder to say that quantum behaviour is somehow "unreal", information-based interpretations aren't clearly favored.
