Thank you Steve. Telmo, before starting to analyze brain recordings ten years ago, I would have fully reinforced your view regarding Turing-complete machine and brain like simulations.
Here is the main problem, we have two distinct categories: a.Scientists whom imagine how the brain works without having direct knowledge of the real brain, they build models, AI theories or simulate "the brain" b. Scientists whom record, analyze data, build brain computer interfaces and try to provide therapy. Even their “access” to the real brain data is highly limited. Between (a) and (b) it is a huge gap. Building a hybrid model as the first step can change this entire trend which started 60 years ago, a fast access to the “real brain” data will be granted for anyone interested to build models, AI theories or simulate the brain 1. We need a charismatic leader(s) and a board of directors to shape the entire strategy build rapidly the infrastructure of the institute. 2.We need reliable ways to facilitate international collaboration, no one whom likes to do research in AI, DL, AGI,...software/hardware development should be left behind. Any idea how to move fast with (1) and (2)?
