" unless someone comes up with a new way of creating such an SI and explaining how he can make it"

The articles I shared answer that question. Of the articles in question, those by IBM and SYNTHETIC INTELLIGENCE | FUTURE OF AI AND TECHNOLOGY are scientific. They are not mere opinions.

Does all this make sense? Well, I don't want to get into relativity. My interest was in passing on information about technology, not questioning whether or not it makes sense.
