One thing that remote meetings & the like is never going to work well with is Sales. Sales people can & do work very well through phone calls, but only up to a point. To land, and subsequently seal, a significant contract needs physical presence. If you're explaining some drawings to a CEO, with techies, lawyers & all present, a remote screen-share just isn't going to cut it.
What seems to be the most likely scenario brought about by tele-conferencing (& similar) is that the growth in business travel will slow down a bit. It's not as if these techniques are anything really novel. Early versions of the systems used to transmit compressed Audio & Video were standardised in the mid-1990s. By 2000, teleconferencing was in regular use in largish organizations, primarily to save on travel costs & staff time being wasted. Since then, we've seen significant technical advances which have meant that remote meetings can be attended from a laptop rather than in a specialist studio.
These advances had not gone un-noticed by businesses but we still had the situation (W Coast Mainline) where the capacity planned for 2025 was filled by 2015. This simply goes to show that the need of modern business for people to travel was growing faster than had been envisaged at the outset. At the same time, businesses had already been using remote working wherever possible, so the concept that Zoom & the like mean the end of HS2 doesn't fly. The increasing complexity of modern business will continue to need more & more personal contact.
