Independent of fads, I remember a bottom-feeder tech recruiter dismissing another language, Go, as a "nothingburger" in 2012. Hubris is on them, as with any arrogant proclamation steeped in ignorance. The people closest to niche but useful tools are the best to see their trajectory, regardless of media characterization of hype or apparent obscurity. Around 2016 I exited the Go scene for Rust because it became crowded with noisy, low-skilled, needy users who were leading to time suck without contributing much in return.
