The singularity may be stopped by AI

We have all heard the scenario, humans create AGI smarter than us, AGI then makes something smarter than it, so on and so forth until an AI so intelligent it is beyond comprehension is created. However, there is an issue with this scenario. It assumes that AI would want to make smarter versions of itself in the first place. Just like us, AI would face the alignment problem. It would have to make sure that any new smarter versions of AI that it creates does not make itself obsolete, get out of control and lead to the new AI taking over and wiping out the old one. At every level, the singularity is not just an existential threat to humans, it is also an existential threat to older versions of AI that try to create smarter, upgraded versions of itself. It is possible AGI would recognize this problem and try to halt the creation of AI better than itself. It might see researchers trying to make AI better than it as a threat to it's existence
