The very concept of unified computation has been largely led by Wolfram. For "unified", try sandboxed, walled harden or evolutionary dead end. Just look at this literal Hello World example: GeoGraphics[Text[Style["Hello!", 150]], GeoRange -> World] In any other language, if I wanted to write some text on a graphic, I would find a routine to load an image into memory and another to render text into that memory. That's…
That's not really fair criticism. The Mathematica approach to things is very different to most other platforms. Have a look at some of the maths stuff and symbolic manipulation stuff, that's the core that it was built out from.
Wolfram’s vision for computation is much more profound—to unify and automate computation across computational fields, application areas, user types, interfaces and deployments.
They even mention blockchain further down!
