I sent them an email asking what .NET version their .NET link library used, asking if it was still .NET Framework or if it had moved to .NET Core or 5+. The question seemed incomprehensible to them. They barely understood what I was asking, and I never heard back from them.

Software is their product, but my guess is there's a separation between the product and research side which will be filled with Phds, and the "build" side which I expect is outsourced or offshored.

What I really mean is that I don't think they see themselves as an engineering company in the way FAANG do, or an "AI" company, but probably more like a maths/science department at a university.
