@paulg This was unpopular at the time I wrote it.

Visibility creates opportunity.
Everyone I talk to says that younger people are not progressing very fast at all (example: junior developer to senior developer, associate to partner, etc.).
This makes sense because so much progression comes from side conversations before and after meetings, direct mentoring in the moment, networking and going for coffee, etc.
The next shoe to fall is that senior people will start being less productive.
Why?
If you already have a large network at the office and established trust (gained from your face to face interactions), working from home was pretty easy. You know who to text or email and what to say to get things done.
When that network starts to turnover .. things change.
With new relationships it will take more energy to get things done remotely. The more turnover the higher the cost of doing business remotely.
I wonder if the longer people work remotely, the more they will behave selfishly. I think as people start to feel less connected to the company and it's people and will start engaging in more me-first behavior.
And one more second order remote thought: If what I've seen with friends who went from office work to remote work is any indication, the longer you work remotely the less tolerance you have for others outside of work. When you work in the office you're forced to interact IRL with people who have different ideas, political opinions, and levels of wealth. When you work remotely a much higher percentage of your IRL time is spent with people who look like you, think like you, vote like you, etc.
If true, the implications of that are huge. Especially for Government, who are required make policy choices for a society they increasingly insulate themselves from.
