I put some money into the Slack stock a few weeks ago based on that thinking, on a lark. Worked out well so far. Any ideas about other companies that will benefit from this inevitable giant wave of remote working that will be growing rapidly for the next 6-12 months?

I think we'll see entire new categories of people working from home on a large scale. Lawyers, marketing people, accountants, etc etc. Basically anyone who is dealing with information rather than physical goods.
