I wonder how this applies to Part Time PhDs. They are exceedingly rare in the US and it usually comes down to having a very supportive Job and an unusually open minded Advisor, I've seen people at UNC and Duke doing part time CS PhDs. It also seems much more common in the UK/EU. I know Oxford, ICL and others offer part time programs.

Seems to have all the upside and none of the downside, you keep your industry pay, continue racking up experience and after a few more years than normal get a PhD to hang on your wall.
