Computers (and frequently their programmers) do not have "judgement", and when they do it will be a short trip to

But I did read an article, where average chess players are beating pros and computer alike by taking advice from, but not submitting total control over to, computers. There seems evident that technology can improve various aspects of performance, but we have to remember that they are all glorified "toasters" and not panaceas.
The point is that technology is neither good or bad, but that it is a toolkit, and knowing when/how to use such a toolkit is the key to improvement/optimization.
