By way of illustration of how far the technology has developed since its early form in screen scraping, it is useful to consider the example cited in one academic study. Users of one platform at Xchanging anthropomorphized their robot into a co-worker named "Poppy" and even invited "her" to the Christmas party.[3][4] Such an illustration perhaps serves to demonstrate the level of intuition, engagement and ease of use of modern RPA technology platforms, that leads their users (or "trainers") to relate to them as beings rather than abstract software services. The "code-free" nature of RPA (described below) is just one of a number of significant differentiating features of RPA vs. screen scraping.[citation needed]
