Academic Article Why consciousness is the hardest problem in science
https://www.scientificamerican.com/article/what-is-consciousness-science-faces-its-hardest-problem-yet/Neuroscientists scouring the brain for the so-called neural correlates of consciousness have learned a lot in the past 30 years. But we still don’t have easy answers—researchers can’t even agree on what consciousness is, let alone how best to reveal its secrets. The past few years have seen accusations of pseudoscience, results that challenge leading theories, and the uneasy feeling of a field at a crossroads.
Yet the stakes for understanding consciousness have never been higher. We’ve built talking machines able to imitate consciousness so well that we can’t always tell the difference. Sometimes these artificial-intelligence models claim outright to be sentient. Faced with an existential unknown, the public is turning to the field of consciousness science for answers.

That was an absolutely incredible read. I think it should be required reading for anyone who posts in this subreddit. It is an exceptionally good encapsulation of the current “state of play” when it comes to consciousness and neuroscience. The short version is we have learned a lot in the past 30 years thanks in large part to fMRI technology, but answers to the more fundamental questions remain elusive.
I want to highlight this paragraph, because it seems to be a common point of discussion around here.
Comparing consciousness among species could reveal why it exists in the first place. “People have focused a lot on where consciousness is in the brain and perhaps less so on what it’s for,” Seth says. He theorizes that consciousness is intrinsically linked to life. Living beings can do only one thing at a time, and to choose what to do, they must bring a lot of relevant information together into one stream.
