Someone is reportedly selling software now to give personal wine recommendations (based on a questionnaire). It's hard for me to imagine a piece of software giving reliable personal wine recommendations, since that requires getting to know your tastes -- but this has been available (for centuries) from good local wine merchants if you have them.
However, it's easy to imagine people selling software that promises to do so. Many of you can remember (before about the 1980s) when computers were much rarer, more expensive, and still had a larger-than-life mystique. This mystique was early exploited to make mechanistic advice look authoritative: The Computer Said It, and The Computer is awesome. Here's an incident I know first-hand. When I was a teenager (when time-shared computers were first showing up in schools, with local terminals) a friend at Berkeley High School said that well-meaning staffers were offering students occupational guidance By Computer. (This friend did volunteer computer support, and had the run of The Computer.) We looked at this small custom software program and it was simplistic, it asked some questions and matched up a simple set of career suggestions, as one might do on paper but faster -- and Authoritative Looking. Unfortunately, students and counselors seemed to take this novel tool too seriously. The Computer Says I am suited for X, so it must be true. So we got to work. Soon the career recommendations began including random odd suggestions -- transplant donor, pencil, etc. -- with the serious ones. Then late in the user session it would increasingly make spelling mistakes and, as it were, slur its speech. Finally it would degenerate to nonsense. It stayed in use for some time that way, but people looked on it differently, maybe even as imperfect as humanity, or more so. (There's demystification for you.)
Most everyone in the wine industry labors to de-mystify wine (especially in places like US where wine is not a widespread tradition), to reduce barriers and increase demand. There's also been a continuum of wine-enthusiastic writers with humor and wit and anecdotes. I listed below some very well known, entry-level wine books pre-1980, most of them published in the US. (I am not a wine-book expert. I have posted all of these before. I've posted wine info sources publicly here for 20-some years for what it's worth. The first public Internet wine-forum posting still public, incidentally, was affordable red-wine suggestions, in early 1982 by Charles Wetherell, who created the wine newsgroup.) For anyone interested, these books have been steadily available new or used (search today by ISBN XXX, or title, at amazon.com or other online sellers, or even a general search engine). One of the best, very useful even now, is the oldest, Saintsbury (1920). The list illustrates longtime efforts at demystification. Mystique is inherent in wine, in the eye of the newcomer. The wine world is thousands of years old, and COMPLEX. Like art, or real estate, or the stock market, or human nature. It takes time to LEARN, though there are aids, including those below and others. Frustration with this reality -- the yearning to short-cut the learning -- is part of human nature too.

-------- "I hope [this] book will stimulate -- especially in the younger generation -- a wider appreciation of wine's many virtues. A knowledge of wines should be a part of everyone's education. To walk about with an Arts degree and be ignorant of wine is incongruous. I could put up strong arguments for including wine in the curriculum of all high schools and colleges." (Blake Ozias, 1966)
