Microsoft announces Python formulas in Excel... which have to get sent to the cloud

This is a most excellent place for technology news and articles.
Kotlin was announced in 2011 and Swift was announced in 2014; that's 3 years apart. Like you said, they do look kinda similar but I think that's the result of being designed with 2010s principles.
Kotlin also didn't launch on a smartphone platform, it just kinda released with the build tools without any initial target platform. Since JetBrain already owns IDEA, the most popular Java IDE, they just bundled that with Kotlin to launch the language. I think it's the opposite, Google piggy-backed off JetBrain's fame and install base in response to the Swift thing instead of also developing a new language. It isn't a lock-in either, JetBrains is quite independent of Android though they did kinda lock the language server to IDEA.
