The thing about this is, that when a new technology truly succeeds the name fades away. The same will happen with .ai or .si if anyone takes that seriously.
We don't call HDTVs that anymore. We just call them TVs. Like what happened when Color TVs became the norm.
At some point a Self-Driving Car will just be a car.
At some point mentioning that a product includes AI will sound silly because it will just be a given.
At that point having ai inclusion be part of the products name will sound as outdated as saying Color TV.
or it becomes the name.
Kodak. Kleenex. PC. etc.
SI has no network effects. I reject it.
It already does sound outdated.
