I was recently watching a video about ram jets (good at mach 3+) and normal jet engines (good up to mach 2). They mentioned that they were just doing engineering, not science.
In many ways, working in web 2.0 feels like engineering. We’ve done it before and it’s just about execution. Web 3, on the other hand, feels a lot like engineering AND science. There are areas, like Subconscious Networks moderation, which have some solutions, but it’s not as well mapped out as it is in a web 2.0 world.
