Earlier quoted context omitted.
I'm well trained in mathematics. It's certainly healthy. However, I often find that outside of their professional work, mathematicians are more willing to part with rigueur than the philosophers across the hall. Notice how most mathematicians aren't particularly interested in foundations of mathematics, for example.
I'm a mathematician working in industry and I'm not at all interested in foundations. That's partly because I trust that all that stuff was worked out in the last century, and partly because there's so much more exciting stuff in math to be interested in instead.
I suppose back around that time and up to a certain time after this happened, most mathematicians were aware of this history, but perhaps they aren't any more, if yours is a representative view.
So then it comes down to interest.
But many mathematicians were interested in foundations around the early part of the 20th Century. Now they're generally not.
This shift makes me wonder how much of mathematical foundations are actually "inherently interesting" (if there is such a thing) to mathematicians and how much has to do with fashion, and if it foundational projects among mathematicians will ever become fashionable (or "interesting") again.
