The "commercial" hype cycle is currently focused on large language models to drive supposedly intelligent programs. In the past years it was cryptocurrencies and before that something else I do not remember. However, behind the scene, developers have their own version of the hype cycles, about technologies or methodologies that, supposedly, would bring computer programming towards a brighter future. These cycles are usually about a specific sector however large, for example there's one for web development, one for editor wars and even one for embedded microcontrollers. Sometimes they even cross-pollinate each others. What's your favourite hype cycle, past or present? The one you consider to have only made things worse? Do you have any funny anecdote to share about failed "upgrades" to a "better" piece of technology? Personally, one of the worst hype I personally experienced was the push for "single page application" websites. It gave birth to bloated messes of code the browser has to execute every time even just to display a line of text. My internet connection is able to download gigabytes of data in seconds, but loading a web page is as fast as it was in 2004.
