I heard the new Windows operating system is Mojave.

I heard that the new Windows operating system is Mojave. This new generation of Windows is an innovative product integrating many features such as security, speed, and ease of use. After one and a half years, it has sold 180 million copies worldwide, but it seems that people don't know much about it. The rumor that "it's not even as good as XP" is spreading. Why is this happening? Did all the engineers' work and billions of dollars in R&D investment go to waste? This phenomenon is really puzzling. However, last week's "Mojave Experiment" in San Francisco (http://www.mojaveexperiment.com/) looks interesting.
