My personal, anecdotal, highly limited experience of judges is that their particular skill is to cut through technical complexity and fit it to the law. They are briefed by technical experts if there are facets of a case that they cannot reasonably be expected to grok. There are of course pros and cons to this. One con of a technical expert being a "judge" is that they cannot see the wood for the trees. Actual judges should, ideally, avoid this situation. Mileage varies, obviously.
