man, i used to be such a gearbox evangelical, but there's still so many hurdles to overcome, and the current 1x drivetrain is \*so\* effective, i'm having a hard time seeing the positives outweighing the negatives for widespread application - in conventional bikes - any year soon.
that said - utilization in e-bike applications may have more traction. added weight & efficiency loss are mitigated by motor power, the gearbox can be better suited to handling the additional torque / wear & tear than a conventional drivetrain, electronic shifting (as opposed to twisters) could be easily implemented since you've already got a built in power source, and the gearbox could be integrated into a nice tidy all in one motor / gearbox / crank assembly. makes lots of sense the more i think about it.
