Seeking your opinion about the future of vintage HPs

[Sylvain Cote]

My take is the distribution look something like this ...
196x-1972 Pioneers - desktop calculators
1972-1978 Early adopters (7 years) - Classic to Spice series
1979-1989 Mass adopters (11 years) - Spike to Pioneer series
1989-1995 Late adopters (7 years) - Pioneer to charlemagne series
1996-2014 No more high tech, computer/phones/tablets/etc have replaced them.

If we take a person at age 20 in ...
in 1972 (begin of the early adopter) will have 62 this year
in 1984 (middle of the mass adopter) will have 50 this year
in 1995 (end of the late adopter) will have 39 this year

I think the peak interest/prices will be between now
and 2029 (15y) and decreasing afterward.

This is to take with a grain of salt of course ;-)
