Absolutely correct assessment by Derek Lowe, who is truly a gem in the field of science journalism.
It seemed that the field was finally moving away from the amyloid hypothesis, but the idiotic approval of Biogen's Aduhelm (after an advisory committee vote of 13-1 AGAINST) has gotten all the pharma companies stupid and greedy again.
I'm not sure I've ever seen a field pour this many resources, for this long, into something that has failed so utterly. It's as if NASA had spent 20 years and $20B on developing catapults to send people to the moon.
