The technology for including hundreds of people in an interactive electronic conference is already available; there is no limit on the number who can be included in one-way communications. Some organizations may find that digital conferencing works well for its stakeholders, and therefore would continue offering it as a format into the future – either as a primary or supplementary way for people to meet.
Most conferences and conventions also include dozens of vendors eager to give prospects a close-up, hands-on look at their offerings – something that would be difficult to simulate online. So we don’t see live, in-person conferences ever completely vanishing.
