Software changes in 7 years - people don't. [I mean the average person; individuals age and get more experienced, but new ones come in.]

Today's homo sapiens brains function the same way as in 2006. Productivity of mental workers responds to disruptions in the same way as in 2006. A large majority of programmers and other people working now in IT are the very same people that were analyzed in 2006.

Brain function is not the only variable at play here. Software and culture change constantly.

Yes, but haven't the tools for working remotely improved a lot since 2006?

Not really - no. I can't think of anything off the top of my head that I couldn't do six years ago.

There are a few more options maybe - but nothing fundamentally different.

They have, but if you look at it in terms of fundamental change, then of course not.

For example, a cell phone from today isn't fundamentally different than a cell phone from a decade ago. They're both computers and can be used to make phone calls. But with the cellphone of today, I can have a virtual meeting with anyone from anywhere, face-to-face. That alone is a huge improvement for distributed teams.
