This is a kind of cute story. Almost every word out of his mouth is complete bullshit, but I'm sure he'll get some clicks out of it. It smacks of "software engineer who knows nothing about industrial controls complains web-dev practices are unsuitable for developing industrial controls".
Incompetent developers are just as great at fucking up projects with Mathworks or Dassault as they are with C. In fact, because the worst spaghetti code you can imagine can be multiplied out to multiple drawn flowcharts without any consequence, even your $185/hr genius contract engineer can't understand his own code two hours after he wrote it. Which is about how long his program takes to compile.
There is a saying, "to err is human. To really fuck things up, you need a computer." Model-based programmers just push this same maxim out to the 3rd dimension.
Not saying it isn't a valuable tool, or that there aren't a lot of really smart people out there doing good work with it. But in my experience the same dumb monkeys typing on fancier typewriters isn't going to make anything better. You just get dumber monkeys.
And because I'm sure somebody will eventually ask...
I use a lot of IEC 61131-3 structured text... looks a lot like pascal at first glance but it is extremely verbose and clunky. Our runtime (Codesys) supports some basic model-based development like ladder logic and function blocks, but I don't know anybody that uses anything other than ST.
Our GUI (dashboard) is Java based, and our smaller controllers are just AVRs.
Our control platform is SIL 2 https://en.wikipedia.org/wiki/Safety_integrity_level
and we use the required features (watchdog, secure outputs etc)
Almost all automotive controllers are similar. They are certainly not in a race to the bottom, but ICE controllers haven't needed more horsepower (so to speak) since 32-bit chips came out in the 90's. Because we make exclusively EV's, our requirements are much lighter. Admittedly, I don't think you could control an ICE in Codesys. Our RT is 5 ms.
I think you can download Codesys for free and play with it but without a hardware support package ($$) from a controls vendor it is quite useless.
