Occasionally I get this feeling for a large customer meeting or a public talk, because there are consequences and serious prep. But this is just trying to normalize extreme social anxiety and call it a management style.
One reason you get together to talk is so you can hash out details on potentially ambiguous topics, so you don't head in the wrong direction causing net negative contribution.
Another is that people are not automata. Humans require inspiration and motivation and you need to reinforce the vision of what you are building and why. Its also even sometimes a reasonable idea to ask about how their life is going and check up on their family and pets and career aspirations.
In general, some people should not be managers, and there is plenty of room in the world for super ICs.
