Watson's performance was characterized by some quirks. In one instance, Watson repeated a reworded version of an incorrect response offered by Jennings. (Jennings said "What are the '20s?" in reference to the 1920s. Then Watson said "What is 1920s?") Because Watson could not recognize other contestants' responses, it did not know that Jennings had already given the same response. In another instance, Watson was initially given credit for a response of "What is leg?" after Jennings incorrectly responded "What is: he only had one hand?" to a clue about George Eyser (the correct response was, "What is: he's missing a leg?"). Because Watson, unlike a human, could not have been responding to Jennings's mistake, it was decided that this response was incorrect. The broadcast version of the episode was edited to omit Trebek's original acceptance of Watson's response.  Watson also demonstrated complex wagering strategies on the Daily Doubles, with one bet at $6,435 and another at $1,246.  Gerald Tesauro, one of the IBM researchers who worked on Watson, explained that Watson's wagers were based on its confidence level for the category and a complex regression model called the Game State Evaluator.

Employment of computer support specialists is projected to grow 12 percent from 2014 to 2024, faster than the average for all occupations. More support services will be needed as organizations upgrade their computer equipment and software. Computer support staff will be needed to respond to the installation and repair requirements of increasingly complex computer equipment and software. However, a rise in cloud computing could increase the productivity of computer support specialists, slowing their growth at many firms. Smaller businesses that do not have information technology (IT) departments will contract services from IT consulting firms and increase the demand computer support specialists in those firms. Employment of support specialists in computer systems design and related firms is projected to grow 31 percent from 2014 to 2024.
