The complexity of a transmission relative to another of the same design is not a function of the number of usable gear ratios it provides.
A clutch-and-planetary hydraulic transmission is just a series of the same basic gear set design. That gear set may be made of exotic materials but once you have one the rest are basically identical. Combining them is only a question of packaging, control, and manufacturing tolerance. All complex on their own but equally important to an ICE.
The linked AA80E from 2007 is an 8 speed. 10 speed designs are not much different.
They’re all fundamentally the same selectively lockable series of gearsets we have had for the better part of a century.
