It’s sorta funny to see one of the companies aiming for terahertz frequencies - long wave IR is only ~30THz.

It'd be nice to see the 'terahertz gap' closed finally.

Not for a practical reason, but it's been on my mind since I randomly found a wikipedia article about it.

Interestingly reading the terahertz radiation wikipedia article they mention peeling adhesive tape generates 2THz and 18THz peaks
