However. When you take into account how hostile the modern office is to IC work, it turns out WFH is much better^. I'm not waiting for the open office to quiet down before getting real work done, and I can just focus whenever I want. 1:1 technical discussions are easier to have, because you just Zoom call the one person, and don't have to go around searching for a conference room. Modern offices are designed so poorly, with such a high level of distraction and low level of functionality, that even WFH without any preparation is much better.
^ Having to take on childcare or not having a private room to work in cancels out the benefits.
