OP, you're selling your tool to the wrong people. HN is not the crowd. This is for core-engineers who want to get value out of coding.
Find people who pay the $1000/yr to use 1 tool in Matlab, and start pulling them away.
Please don't try and box the user base of a web community. It's exclusive rather than inclusive. You have no idea who is reading these pages.
It is less so OP's tool, and more so the way they presented it.
I won't discourage them away from SWEs. Instead, I want to encourage them to sell to core engineers. I was a MechE for the longest time too. And this is a great Matlab alternative. In fact, I was exactly that MechE who was using HN to feel like a part of the tech community.
The top post is phrased as a sell. But, if I'd read it during my MechE days then it would've gone right over my head.
There are plenty of that type of person here on HN, we're not all engineers.
i.e. some of us are engineers in the traditional meaning.
I wonder how many "traditional" engineers are Mac coders. I work at hp so not many Macs around but in our R&D and especially in manufacturing and test&measurement Mac-only would be a problem.
