There are many theories linking consciousness and quantum physics, and it's important to say that this research doesn't prove any of them. However, if the research can be replicated in a proper peer reviewed way, it will provide startling new correlations between observed effects of consciousness and quantum physics.
These tryptophan networks are common in microtubules, structural components widespread in all cells. Although no one knows why anesthetics cause people to lose consciousness, there is evidence for them having effects in these microtubules. There is also existing research that seems to show correlations between quantum behavior in these microtubules and the actions of anesthesia. With this fresh research, now it seems there may be a further link between these microtubules and quantum physics.
Its possible implications for AI may be huge too. Some assume current approaches to AI will lead to some form of machine consciousness; this suggests that belief may be misplaced, as 3D structures like microtubules may play a role in creating it.
This illustrates the problem I always have with these discussions. It's even more frustrating in this article, as it clearly states facts, but in the most cowardly of fashions avoids honest implications. How are we supposed to have a free market economy based on capitalism when there is zero value for labor either physical or intellectual?
Every single part of our financial system is based on that; from banking to mortgages to consumer spending to the stock market having valuations to property having valuations. If every single job you can imagine, even the future ones, can be done by machines that are vastly cheaper than humans on the minimum wage, you cannot possibly have an economy that is anything like today's. Yet cowards that they are, the authors of this article lead us all they way to that conclusion, but are too scared to say it.
