Now what would be plausible is if we could get 10-20% of the workforce remote, and thinking about what that looks like. It might mean that at a remote-friendly company, something like 50% of the staff is remote so we need tools to help remote and in-office employees work better together.
It could also mean that parts of traditional organizations get broken into independent services. x.ai and clara labs both are great examples of how part of a traditional assistant's job is handed off to tech, but the same approach could be used to hand work off to remote employees. This would enable companies to hire fewer people for the in-office tasks, but it requires a rethinking of what each role's responsibilities are and might include sharing an assistant amongst a few execs rather than each having their own. These changes could have a big impact, but don't come directly from new technology. Still, I think they are worth considering when we imagine a more remote workforce.
EDIT: Also if you have the skills to work remote (or partial remote) you will never want to go back to the old "must be in the office every day" job again ;)
The main problem here are power distribution and network connectivity.
Mobile data is an unfeasible option as monthly quota would be just too little, and there are some basic requirements in terms of bandwidth and latency (think of video-chatting with colleagues -- for example, during meetings).
