In the first few years looked at JOAS mentioned how there was an increase in membership from the website
There's almost a doubling of numbers from 2005-2010 - my personal hypthesis was the Publication of Works of Satoshi #1 in 2005 put his creations in the spotlight, increasing interest in the art.
Even if the numbers continue to fall for 34, we have a stable plateau, if with a slight upwards trend, from 2010 onwards.
Membership may be down from covid numbers, but I suspect they'll be echos. Something will capture the zeitgeist, people pick it up again.
I predict that origami will settle in a happy medium - like the shallow seas of the Permian, we'll see a lot of bubbling of creativity with spikes here and there.
