I mostly agree with you, but you couldn't have have meaningful live videochat between continents in 2000.
CuSeeMe certainly was being used before 2000.
That took until skype in 2003 I guess. The idea is pretty old though and people were trying for it for a while from different angles.
Maybe not between continents but we had meaningful live video chat in 1968
CU-SeeMe worked pretty well in 1995 if you had access to a half decent Internet connection, which admittedly most people didn’t.
For well funded organisations, ISDN video conferencing facilities were reasonably common.
