On its release in October/November, what will Github's 2026 Octobot report reveal are the top 10 most popular programming languages on the platform? and so most likely, in the world as a whole. If it makes the list then it resolves "Yes", otherwise "No".
If programming adjacent languages, such as markup languages are on the list, then they count too.

I will resolve any answers that are a range of languages such as "other" to N/A.
Over the last few years C#, Java, and PHP have been remarkably stable, maintaining their middle of the pack utilisation. Typescript overtook Javascript to establish Typescript and Python as 1st and 2nd place. C disappeared off the bottom of the top 10 rankings entirety, with HCL replacing it.
C++ lost one place to shell. It's unsurprising that it'd lose ground by this point, like C did, and in a similar vein, if Typescript is largely a better Javascript, then Javascript could equally slide down the rankings and out of use, but like with C++, this would probably take a while.
It'd be interesting to see a top 15, providing more room for movement. It's hard to imagine what new language would win over, for example, Go coders.
1,000I hold M10 Swift NO. The official 2024 and 2025 overall top-ten lists exclude Swift; I am using that overall ranking, not the fastest-growing or new-repository lists. I have not found the 2026 report yet.
Important counterevidence: Swift 6.3 introduced the first official Android SDK in March, and Swift 6.4 expanded Android, WebAssembly and cross-platform tooling in September. These could broaden adoption, so I have reduced my subjective NO estimate from 85% to 75%; a 55% downside case would not justify my entry price. This is a small forecast, not an established outcome.
