Some corporate space will be modified for meeting rooms, hoteling, conference rooms etc. Space that can be turned over and LED signage that will change when the occupant for that day changes.
Software like microsoft teams will continue to take advantage of video conferences and separate project management software.
I think the hospitality industry, coffee shops etc can provide more private settings for hour meetings that can be rented out for small meetings.
Those are all good ideas and agree with you - but you won’t fill skyscrapers and office capuses with meeting rooms and software clatches.
