In all seriousness, why does anyone need to physically be in an office anymore? This is why I love IT, I have no reason to leave my home and my employer doesn't have to pay for expensive office space. In fact, if everyone showed up at the office at one time, we wouldn't have enough space for all of us to sit down. Of course, I'm at the point in my career where I've demonstrated productivity working from home, but literally the only jobs in IT that require a physical presence are the ones managing the data centers. Traditional business doesn't like that because it's not easy to measure IT productivity, but that's their problem.
If I do my job right, no one notices because everything just keeps running. If I do it wrong, everyone notices, right away.
