Well i belive its just like the car industry. BMW, Mercs, Jags, TRD, Nizmo are all on the cutting edge of technology, after a while it filters down to the common user as a standard not a option.
for instances Adaptive optics is only in use on some really high end gear with multiple mirrors. who knows we might soon have that same ability to have a half meter + mirror system in a dome for not much more than 5k in the next 10- 15 year.
As always things take time and the chinese make that time frame shrink!
god bless there little souls for giving minions of the stars like me the chance to get decent mirrors for diddly squat!
