I've been working remotely the last decade or so, you could not be more right, and this is one of the core topics on communication training on every company I've worked for. For this reason, companies are also nowadays, as per my observation, emphasizing the requirement of "excellent communication skills" on their job advertisements. It's not the sarcasm obviously, it has to do with the communication as a whole. For this reason, as well, I've noted that increasingly cameras are preferred in remote work setting. When I started working fully remotely, in 2010, cameras were used much much less than today. At least in the companies I've worked.
