As it stands I feel like we're going to have to wait until all Silent Generation/Boomers retire before we can see real progressive change in this area.
Honestly it really speaks to poor management in general. If your only measure for project progress is "butts in seats," then you have no idea what is going on below you. It isn't like slacking off while physically at work isn't basically a meme already.
Companies would actually be more efficient if they communicated progress/expectations in a trackable way, telecommuting just forces that issue, but it is an issue regardless of where people are.
