John Brownlee traces the rise and fall of steampunk, a genre and aesthetic I know is close to many hearts 'round these parts. (Some of my own thoughts on the matter are quoted.) The arrival of smartphones was a key moment, he writes, putting technology permanently within reach — and beyond it.
Divorced of their gear-cog trappings, the best parts of steampunk live on as a wide-scale design and political movement known as Right to Repair. This movement, which is picking up steam among state legislatures (and vehemently opposed by major tech companies like Apple), is ostensibly about combating forced obsolescence and breaking the modern consumer electronic upgrade cycle, through legislation that forces companies to make their products repairable by the end user. In other words, it's about empowerment and transparency: the right to understand the technology you depend upon.
From that perspective, steampunk never died at all. It just lost the "Jules Verne goth" aesthetic and went mainstream.
