For someone entering tech, everything they see is new and exciting and mystical and hard to understand. Without prior context, it's hard to see why overengineered crypto nonsense is different from all the other overengineered nonsense they're learning about at break-neck speed. For many of them, the only reason to enter tech to begin with is to earn a decent living. They lack the technical background to understand if what they're being paid to build is a grift or a legitimate business, and in the current market, it's increasingly in their best interest to not understand the difference.
I believe we lost when we collectively accepted "software is eating the world" as an inevitable positive maxim of our reality. In retrospect, it seems self-evident that the end stage of this ideology-slash-self-fulfilling-prophecy is a socially-legitimized software-based "value" chain that ingests raw wealth and produces absolutely nothing of value.
