I don't think a true company - one that builds sustainable value - can ever only exist online or remotely.
Very few entrepreneurs start their business on the back of market research. Instead, they have tremendous zeitgeist, honed by paying attention to where they are.
All businesses and jobs depend on a vast number of people, often unnoticed and unthanked, without which nothing really gets done. They are all human and deserve respect and gratitude.
The cell phone has become the adult's transitional object, replacing the toddler's teddy bear for comfort and a sense of belonging.
The best remote companies I've seen do almost everything online, via email and telephone. But they also get together face to face on a regular basis.
I regularly take my entrepreneurship students out walking because I want to get them in the habit of noticing and thinking about what they notice. They have to leave their phones behind to learn the basic lesson: Be where you are.
