I discounted the remainder of the piece after reading this:

  Personal freedom. As a PhD student you’re your own boss. Want to sleep in today? Sure. Want to skip a day and go on a vacation? Sure. All that matters is your final output and no one will force you to clock in from 9am to 5pm. Of course, some advisers might be more or less flexible about it. . .

For some programs, this is untrue. Your advisor, your experiments, or your conference deadlines govern your schedule.
