We're living in a world where we have 7.7bn people on the planet. 85% of them are literate. A large proportion of those have access to the internet in at least some form. This gives them (theoretically) access to the entire cumulative knowledge of the world, as well as to each other.
And the pandemic has given people the world over a new sense of collectivism. We all share one planet and risk each others' misfortunes.
This allows people to organise, with comparative ease, global movements around common causes such as saving the environment or defeating the pandemic. (As well as to spread nationalism and other arguably less desirable ideas.)
In the knowledge sphere, organisations will be able to look for the best employees and partners across the whole globe. Similarly, individuals will be able to compete for jobs on a global scale.
