I am 53. I have worked at home or at an office, and they both have advantages; the ideal would be a few days of each every week. A mix of veterans and rookies is a good way to encourage a mix of old and new ideas, and also enough questions being asked (and people explaining to each other how things are supposed to work). I do worry a bit about onboarding of rookies into workplaces when it's all WFH; you can always ask for help but it's not as good as having a person sitting at the desk next to you. Large or small companies both have their advantages, but small companies are more likely to allow a variety of tasks to be done by the same person; employees at large organizations are more specialized.
