"Hubert Dreyfus, who argued that computers, who have no body, no childhood and no cultural practice, could not acquire intelligence at all. One of Dreyfus’ main arguments was that human knowledge is partly tacit, and therefore cannot be articulated and incorporated in a computer program. "
I have not read the rest of the article but in the introduction it's stated:
"The article further argues that this is in principle impossible, and it revives Hubert Dreyfus’ argument that computers are not in the world."
Wiktionary defines tacit as "Not derived from formal principles of reasoning" [1].
So the main argument is that humans have intelligence that is impossible to express through reason or codification. In other words, humans have a literal soul, divorced from physical world, that cannot be expressed in our physical world thus making any endeavour to create artificial intelligence impossible.
This is a dualist line of reasoning and, in my opinion, is nothing more than theology dressed up in philosophy.
I would much rather the author just flat out say they are a dualist or that they reject the Church-Turing thesis.
