I hope that all-remote work environments will rise in popularity and level the playing field. Not only for introverts, but also for people with disabilities that make it difficult to participate in casual conversation. I dream of an environment where a deaf person, a person with a severe speech impediment, an autistic person, people with other disabilities that don't prevent one from making small talk (e.g. blindness), and yes, some people with no severe disability can all work together, without necessarily even being aware of each other's conditions, because they're all working remotely and using text to communicate and get their work done.

Disclaimer: I work in accessibility, and am legally blind myself, so maybe I fixate too much on disability-related issues sometimes. I can make small talk at the office though.
