Evolution is not exactly a random walk, it&#x27;s a lot better. But it&#x27;s plausible that creating an AI more &quot;intelligent&quot; than humans (whatever that means) is beyond our current intellectual capabilities, although I seriously doubt it.<p>He&#x27;s forgetting two other scaling modes applicable to human intelligence: accumulating knowledge and collaborating. By accumulating knowledge we can build upon the work of the generations before us and take essentially unlimited time to crack a problem. Collaboration allows not only parallel processing of problems but also interacting and exchanging inspiration towards the solution of a single problem; both which scale quite well with a lot of intelligent people.<p>Note that there are almost trivial arguments showing some problems are beyond the means of our finite brain (viz unbounded algorithmic complexity or the halting problem).
