Here's what I don't get about this though, was there less meetings back in the early 2000s? I'm only 24 so I don't know, but if there is one thing I feel has been passed down from seniors as a software developer it is that in the early 2000s managers loved holding meetings.

You're right, there have been companies plagued by meetings for a long time. The difference is the kind of work we do. Now it's mostly "knowledge work" and service work. Parkinson's law--work expands so as to fill the time available for its completion--is probably the culprit these days. As long as people can complete their jobs before the deadlines, they will also tend their virtual farms and talk about nothing with their coworkers at the virtual water cooler on Slack. It's no longer cool for employers to tell their workers to get back to work and stop talking and playing games.

Excellent point. Let's schedule a meeting to discuss this further.

Productivity measures how much money economy produce per hour of work. It depends mostly on type of industries and such and little on how persobally productive white collar worker is.
