Interesting... I wrote a similar post about MATLAB's syntax a while ago, and I still think MATLAB is one of the best calculators on the market.

RunMat is an interesting idea, but a lot of MATLAB's utility comes from the toolboxes, and unless RunMat supports every single toolbox I need, I'm going to be reaching for that expensive MATLAB license over and over again.

Yep! Makes sense. Though I think the cost of writing these toolboxes is lim --> 0.

Will have a really solid rust inspired package manager soon, and a single #macro to expose a rust function in the RunMat script's namespace (= easy to bring any aspects of the rust ecosystem to RunMat).

I wouldn't be so sure that writing those toolboxes is cheap. You need an aerospace engineer to write the aero toolbox, or you are going to miss subtleties. I assume you need a biologist to write the biology toolboxes. All of these domain experts are really expensive, and I would not trust a toolbox that hadn't been review by them.

Even then... the reason we use the aero toolbox is because everybody in the aero industry trusts that MATLAB's results are accurate. I don't need to prove that the ECEF<->Keplerian conversions are correct, I can just show that I'm using the toolbox function and people assume it's correct. The aero toolbox is trusted.

When I've had to write similar code in Python, it's a massive pain to "prove" that my conversation code is correct. Often I've resorted to using MATLAB's trusted functions to generate "truth" data and then feeding that to Python to verify it gets the same results.

Obviously this is more work than just using the premade stuff that comes with the toolbox.

Any MATLAB alternative faces the same trust issue. Until it reaches enough mindshare that people assume that it's too popular to have incorrect math (which might not be a good assumption but it is one that people make about MATLAB) then it doesn't actually mimic the main benefit of MATLAB which is that I don't need to check its work.

It's funny that you listed 1-based index as a strength, and another poster here lists it as a weakness. Goes to show there's really no agreement when it comes to indexing!
