Either I miss something, or is it yet another marketing approach by Stephen Wolfram? The post talks about "foundation tool", yet it offers an MCP to a proprietary app (out of miriads of such).
Sure, as any other tech, Mathematica may have its edges (I used it deeply 10-15 years ago, before I migrated to Python/Jupyter Notebook ecosystem). But in the grand scheme of things, it is yet another tech, and one that is losing rather than gaining traction.
Certainly not "a new kind of science".
Stephen Wolfram doesn't claim that Mathematica is a "new kind of science"; that's the slogan he uses instead to refer to the theoretical physics model (one based on state transitions) that underpins his 'Wolfram Physics Project'.
