Good probably in the long term if you factor out corporate greed and
assume ( as in fight for) legislative spectrum protection.  At the
present rate of technology HF spectrum will be of little use to
commercial interests anyway not too far down the road.

Equally boring ( as in time wasted while I nap) are some new, wet ink,
engineers that cant even figure simple Ohms law problems without a
calculator.
I work with one real "piece of work" that I finally did the calcs, made
the changes, got the plots and THEN asked him for the values. A few of
the Sr Engineers are starting to catch on to my "in flight" methods.
