I think something that's not readily apparent with the success so far of remote work during COVID, is that organizations are operating on the organizational 'shared context' that was created before remote work started.
It's why I think outsourcing often doesn't work out. Outsourced workers lack an understanding of this shared context which makes for a high level of friction and impairs their ability to deliver the work as imagined by the organization.
Right now, IME we're still in the sweet spot of being able to work from this shared context, which I think means the benefits of working from the same physical space are not appreciated.
It'll be interesting to see how things play out if remote work becomes the norm. I do think remote work can be successful, if the effort is put in to make sure that collaboration etc. still occurs. However, if companies stay remote and try to run on the fumes of the previously held shared context from pre-COVID then I think it will mean disaster for them.
