I have kinda noticed the opposite.
It sure seems to me as though there's a huge demand and massively inflated prices for desirable manual machines. Things like modern era 4" HBM's and 20x120 manual lathes are sky high or unobtanium right now.
I think the machines that hobby folks glom onto have lost some of their pandemic inflated value, but real money earning machines that can counteract supply chain setbacks are worth more than ever right now.
I watch the values of things like work trucks, dump trucks, forklifts and machine tools pretty close. I have noticed less desirable stuff selling for more realistic prices while premium/desirable stuff is still selling for top dollar.
A used 8k-10k lb capacity telehandler is still a $35k- $50k purchase around here. An older used 4k lb forklift is down around $2500 where it should be while anything that can lift 4 tons and up is still above $1/lb lifting capacity and selling instantly. An old beat up morse taper spindle 4" Giddings and Lewis is a $3500 HBM whereas a 70's HBM with rotary axis and digitals is a $35,000 machine.
I think the pandemic brought a lot of value to junk somehow that should never have been so valuable. That is going away quickly, but the values for machines with strong earning potential are tied to inflation and steadily rising.
