> does a human at the other end of a high-latency video call not have AGI because they can't react any faster that the connection's latency would allow them to have

Correct. A person who'd mentally operate that slowly would be considered to have some cognitive disability. For example, would likely not be allowed to drive a car.

You could be fooled in thinking it is a human behind a slow connection, but layman would not consider it real AGI in my opinion, since you have to handicap the human, it seems like lowering the bar just to pretend you reached AGI.

You might recognize it's pretty close to AGI, if it has all the other qualities, but it needs to also operate at a similar response time, uptime, and so on.

My point is, everyone that's not trying to build AGI defines it as, same as an idealized smartest human would be in every way. I truly think this is how most people imagine AGI in their head, and until you have that, they'll say it's not AGI, and industry folks will claim the goalpost keeps moving, when in reality they kept setting their own post.
