- open layout offices are awful places to work where many people struggle to focus at all, to the point where their work is negatively impacted
- separating home location from work location opens up opportunities to work places certain people would never have considered before, unless they wanted to leave their friends/family/social groups/etc. behind
- cutting out a commute every day saves folks time, money, stress, and likely cuts down on a lot of wasteful greenhouse gas emissions
I'm relatively early in my career, but I also love WFH compared to in-office work. Why? I hated the commute, I don't like socializing with my coworkers outside of actual work, and I struggle to focus with folks on calls around me and without decent thermostat control. I acknowledge that some people can deal with all of those things, still be productive, and reap the benefits of in-person work. But there are also those of us whose careers have skyrocketed in the past couple of years specifically because we have a working arrangement that works better for us now.
It's hard to say how much this will impact my career trajectory in the long term. But I'm also more concerned about my private social life and hobbies than I am about my career, and remote work works far better for that, too.
TL;DR: Different strokes for different folks. Young people are not doomed by remote work.
