We don’t need Searle’s thought experiment or any other to argue against this possibility. All we need is an appeal to the real, actually existing world. In this world their is still no such computer despite almost 70 years now of hope, belief, and seemingly never ending hype. All the hype and hope in the world can’t change the fact of the matter, which is that there is no AI, and maybe never can be. Just look around for all the evidence you need. Of course I am sure it is just around the corner, or next year, within five years for sure, definitely this decade, absolutely for sure this century, someday for 100% certain, no takebacks, maybe.
