I'm using technical in a broad sense. One effect of scientific research becoming bigger is that roles are becoming more specialized. Often the people leading the research have primarily spend time writing grants or papers, and less senior professors and post-docs will carry out the actual tasks. When I first started I was a bit shocked at how many of the big names knew basically nothing about the process of how their own research is carried out.

The effects are more pronounced depending on what field we're talking about. For example, in physics, I'd imagine most people have at least the fundamentals of programming down, even if software design may be lacking. In the field I work in (Neuroimaging), a lot of PI's are doctors or neuropsychologists, and might barely even know how to use a computer.
