Really, what? This is horseshit of the highest order. Why would you think this is true? The vast majority of automation tasks don't require advanced AI. The vast majority of human work can be removed without recourse to AI.
In addition, AI produces enormous problems, especially in the colossally power-imbalanced society we live in. It's overwhelmingly likely that an AI would be used first for surveillance and oppression; this is probably already happening with the most sophisticated intelligences we have available to us.
Finally, there is a superabundance of "intelligence" available to us already, in the form of human intelligence. These intelligences are already highly capable of understanding and solving problems that an AI would take generations to appreciate on human terms (if it ever could)
To me, the most positively impactful thing that we can do as human beings is to enable the full application of human intelligence to solving human problems, currently going to waste in most corners of the globe.
