It seems that every time someone invents a new hammer, people use it to solve every problem, whether it's the right tool for the job or not. When viewed through the lens of hindsight, the advertisements are quite amusing.

In the 1890's it was "electricity." In the 1920's it was "radio." In the 1940's it was "radar." In the 1950's it was "atomic" everything. In the 1960's it as "space" this and "space" that. In the 1970's it was "jet." In the 1990's it was "cyber." Today, it's "blockchain" and "AI."

Some of it works. Most of it is snake oil. But people keep buying based on trendy keywords. People are just built that way.
