Kind of like they declared "this is what life is", and they were probably right to do so. Vitalism and dualistic theories of consciousness both belong in the dustbin of history.
Science adopted materialism as it's guiding philosophy prematurely. We've since added electromagnetism and quantum theory to science, but still the hope for the falsification of vitalism persists.
One could argue that, epistemically at least, a mathematical monism might be better placed as a foundation, but that doesn't change any of the facts we've discovered based on materialism.
If you're in fact arguing for some sort of dualism, there is little reason to accept it beyond unconvincing philosophical speculation.
So on balance of evidence, there is little reason to think dualism will ever be required and considerable reason to think it will not. So much so, that I firmly stand by my original statement.
To clarify the "unconvincing philosophical speculation", I meant thought experiments, like p-zombies, that are supposed to convince one that there is something more to consciousness than can be captured by materialism, but which primarily appeal to vague intuitions and make use of semantic tricks of natural language to convince people that there's something of substance going on.
No, but we realized that we don't need a definitive answer to recognize that there's no secret sauce as vitalism would require us to posit.
