This is like saying offices can make a comeback after the industry went all in en masse for open plan. The stated reason for open plan was the mythical 'organic interaction,' but in reality it was reduced seating costs.

Remote work takes that those seating costs right to zero, and it's already been proven out with ample data demonstrating that productivity suffers little, if at all. There are a plethora of multi-billion companies that are 100% remote to really drive this point home.

In-office work isn't coming back any more than personal offices with doors for individual contributor engineers are coming back.
