Ben Goertzel in response to some common objections covered in an article on io9 by George Dvorsky ‘You’ll Probably Never Upload Your Mind Into A Computer’: http://io9.com/you-ll-probably-never-upload-your-mind-into-a-computer-474941498
Objections are covered in order as they appear in the article:
1. Brain functions are not computable.
2. We’ll never solve the hard problem of consciousness.
3. We’ll never solve the binding problem.
4. Panpsychism is true.
5. Mind-body dualism is true.
6. It would be unethical to develop.
7. We can never be sure it works.
8. Uploaded minds would be vulnerable to hacking and abuse.

Blurring lines between man and machine.
A breakthrough has made way for a new paradigm in bioelectronics. Earlier, it took the implantation of physical objects to initiate electronic processes in the body. Humans have incorporated technology to enhance the human experience and take charge of their evolution. They’ve also integrated devices within them that could alternately function as organs when biological tissues fail.
Scientists have now developed a viscous gel that will be enough in the future.
Researchers at Linköping, Lund, and Gothenburg universities in Sweden have successfully grown electrodes in living tissue using the body’s molecules as triggers.

How the Big Bang gave us time, explained by theoretical physicist Sean Carroll.
Up next, The Universe in 90 minutes: Time, free will, God, & more ► https://youtu.be/tM4sLmt1Ui8
In this Big Think interview, theoretical physicist Sean Carroll discusses the concept of time and the mysteries surrounding its properties. He notes that while we use the word “time” frequently in everyday language, the real puzzles arise when we consider the properties of time, such as the past, present, and future, and the fact that we can affect the future but not the past.
Carroll also discusses the concept of entropy, which is a measure of how disorganized or random a system is, and the second law of thermodynamics, which states that there is a natural tendency for things in the universe to go from a state of low entropy to high entropy. He explains that the arrow of time, or the perceived difference between the past and the future, arises due to the influence of the Big Bang and the fact that the universe began in a state of low entropy.
In a recent study published in Cell, researchers presented eight hallmarks of neurodegenerative diseases (NDDs), their in vivo biomarkers, and interactions to help categorize NDDs and specify patients within a specific NDD.
Despite being linked to rare genetic forms, all eight NDD hallmarks (cellular/molecular processes) also contribute to sporadic NDDs. In addition, they contribute to neuronal loss in preclinical (animal) models and NDD patients, manifesting as an altered molecular (hallmark) biomarker.
An NDD patient could have defects in multiple NDD hallmarks. However, the primary NDD hallmark depends on the NDD insult and the neuronal susceptibility and resilience, i.e., one’s ability to handle insults in the affected brain region.
Scientists have identified the exact point at which healthy brain proteins are shocked into the tangled mess that is commonly associated with Alzheimer’s disease.
Researchers at the University of California Santa Barbara (UCSB) are h opeful that the new laboratory technique behind the discovery can be used to directly study the ‘never-before-seen’ early stages of many neurodegenerative diseases.
Tau proteins are abundant in the human brain. At first, these proteins look like tiny pieces of string inside neurons. As they fold and bind together with structural elements called microtubules, however, they create a sort of skeleton for brain cells that helps them function properly.
Glioblastomas are the most common malignant tumors of the adult brain. They resist conventional treatment, including surgery, followed by radiation therapy and chemotherapy. Despite this armamentarium, glioblastomas inexorably recur.
In a new study published in Nature Communications, Isabelle Le Roux (CNRS) and her colleagues from the “Genetics and development of brain tumors” team at Paris Brain Institute have shown that the elimination of senescent cells, i.e., cells that have stopped dividing, can modify the tumor ecosystem and slow its progression. These results open up new avenues for treatment.
Glioblastoma, the most common adult brain cancer, affects 2 to 5 in 100,000 individuals. While the incidence of the disease is highest in those between 55 and 85 years old, it is increasing in all age groups. This effect can’t be attributed to improved diagnostic techniques alone, suggesting the influence of environmental factors hitherto unidentified.

Scientists can finally explain the ‘breakthrough’ experience.
Year 2021 Basically dmt may be a sorta chemical based computer that shapes our reality which could help understand why sometimes people have disorders of reality perception.
Do we see the world as it really is, or are we creating our own reality? We delve into the neuroscience behind the world that we experience.
