This is quite an unfortunate article. Author goes on to list several folks who don’t have PhD but have “made it” and asserts that many people can do fascinating and cutting-edge work without PhDs. There are always outliers in stuff like this but ask yourself: How many people you know who don’t have PhD and have freedom to explore at work full time what truely interests them? Author has rather twisted view of the selection bias.

People should do PhD if they are genuinely interested in doing scientific research. If you are doing PhD under pressure or in hope of getting better paying jobs you will be dissopointed. It is an arduous process and taking up your precious years but it gives you opportunity to have freedom to explore and work on your interests for rest of your life. You won’t be coming to office everyday doing assigned task on your backlog and reporting your status in scrum meeting. Instead you will be reading about new creative work that was literally published yesterday, mulling over that in lunch with colleagues and apply your original ideas to actually get published under your name. The downside could be lower pay and/or no stock bonuses for many outside of hot areas like AI. But in general, you have much better chance of doing cutting edge work that you are truely passionate about if you have PhD in that area.
