I see what you mean. It's not entirely unrelated - an example of such an object is the theoretical mass at the center of a black hole.

From inside the black hole, it is theorized that everything is substantially 'singular' - as in literally pulled into a singular high-density mass for which the gravitational forces are so great that they even pull in light and generate the event horizon that we perceive from the outside.

The way this relates to a technological singularity is that a sufficiently advanced AGI will theoretically access/interpret/monitor/design? all other technologies, creating a technologically 'singular' entity/ecosystem/whatever we call it at that point.

My comment was just to emphasize that the boundaries of what a 'singularity' is are very fuzzy, so while the sub may eventually agree that AGI exists to fulfill the general definition of a technological singularity, at the same time (i think) we will always be identifying technology not yet joined to that singularity. Eventually, we may even pivot to discussion of an extra-technological singularity as well.
