While much of what is going on is a marketing exercise, there is some good news. It is only a breakthrough, however, if you haven't already encountered Mathematica, as it is mostly a port of the Mathematica scripting language to the cloud plus some additional libraries such as an API to use Wolfram Alpha.

After spending a lot of time agonizing about what to call the Mathematica scripting language it was named Wolfram Language and it has been claimed as a breakthrough. The real mystery of Wolfram Language is why it took Stephen Wolfram so long to realize that it was possible to get a wider adoption of Mathematica by making the language more important than the program. but if you get hooked the bill increases quite quickly.

The next step in the conversion of the Mathematica symbolic math package into a programming language has just been launched - Wolfram Programming Cloud.
