Swift has a big potential in the sense that it's backed by Apple, and looks like Objective C reimagined for Apple's purposes.
Rust has Mozilla backing, and it's already popular around here, so I won't elaborate.
Extra points for naming languages which will succeed despite not being initially corporation-backed.
WebAssembly will be really interesting. It could finally be the tech layer that replaces the JVM. I'm not sure what the winning language will be though.
love the concept tho
