Is This the Future of Software Development?

Maybe the advantages come with some disadvantages, which wildly gushing articles like this ignore?
OK, there's a new Smalltalk on the market. Unless it knows what the previous disadvantages were, and has fixed them to the satisfaction of developers, Smalltalk isn't going anywhere. This article gives no hint that they even recognized that there ever had been disadvantages.
Smalltalk is not the only language to face this dilemma. Nearly every new language that comes to market does, as well. For example, Ceylon, Clojure, Crystal, Dart, Elixir, Haxe, Julia, Nim, Rust.
All programming languages have disadvantages. They don't need to be "fixed" in order to be useful and accepted. You think Java, Python, and JavaScript are perfect? How about Go, Kotlin, and Swift?
So it's not just comparing programming languages. And for each language there are a multitude of toolchains for solving these other factors. If you find the most efficient of each of those and compare as well as other factors not even mentioned (e.g. how do multiple remote developers work on an image?) the picture will be quite different.
