Generally yes having a very high performing member on the team is a good thing. However there are situations where it can cause problems with the team morale and dynamic. As well as sometimes very serious/catastrophic issues. Say you have a team with several good performers and one very high performer that just blasts through their work. This can (and usually does) lead to other members of the team feeling they're not as good. This can lead to them backing away from tasks they are good at, feel they're 'not good enough' and looking for another job (a loss for the team as they were good). It can also cause friction as the very high performer will often snap up many tasks. Tasks which other members of the team may find interesting to work on. Again leading to morale issues. Another point is that you should ask yourself how is this person performing so much faster than everyone else? Are they cutting corners? Are they not planning things and introducing awful technical debt you will have to deal with in a year or two when they have left from boredom? Do they have some undiagnosed/unmanaged neurodivergent trait such as ADHD that may lead them to burnout? Are they 'throwing themselves into work' because of personal issues that may lead to a house of card style collapse if they reach breaking point? Are they abusing drugs? Over the years I have worked with a few very high performers because of some of the above reasons. I am not saying all very high performers have something from the above list, there are just some people that are like machines on overdrive and always have been. But many times there is a reason behind it and a good manager will identify that for everyones benefit. In my personal experience the very high performers I have worked with had a mixture of personal and drug issues. One of which lead to a terrible outcome that destroyed their career and family. For a couple of years they were the "rockstar 10x programmer unicorn" people dream of having. But over time problems become more common, internal team issues were almost all this persons fault, etc. They went from being a rockstar to a tremendous liability and resulted in several team members leaving due to the hostile environment they created.
