Here are mine: 1. Still no level 4/5 autonomous cars anywhere in sight. The promise of being "just around the corner" fizzles down and people just forget the hype. 2. Same with AI. The panacea hype dies down. No AGI at all. No major job losses due to AI automation. 3. Facebook (the SN) still exists but ages along with it's current user base. i.e it's the "old people's" SN. Facebook (the company) is still going strong…
Based on something like the Gartner Hype Cycle I will guess that we might be nearing something in 10 year. Or it might be that these things work in a 30-40 year cycle (based on observations of the last time AI was hot).

For better (we can use languages that doesn't have more built in footguns than PHP) and for worse (openness of frontend will disappear) WASM will make Javascript unnecessary in the long run.
I'm kind of seasoned with JS - and a number of other languages - and the only real strength that JS has compared to TypeScript, C# and Java, language wise, is that it is ubiquitous.
Besides: if you get developers tp agree on a single stack in 10 years then you are dangerously good at negotiations and should spend your time in embassies not on HN;-)
