Systems are typically fragile because of poor system design not language choice. I've worked on many C and C++ systems and there's nothing inherently more robust about them. Some would argue that the various ways you can trip over UB makes them more fragile...
That is definitely a factor! But I probably wouldn't pick C++ for a medical device now anyway - I would go with Ada or Rust.

Poor system design and language choice are both factors. You can work around language choice with a shit load of testing, but it's still much better to use a language that gives you stronger guarantees. Also the choice of language affects system design, so it's not like you can just ignore it.
For example even ignoring anything memory related, Rust's borrowing system pushes you towards code that has fewer bugs. Python... well, not so much!
If pointing out relevant and real differences between languages counts as "bashing" then I'm not sure how you are meant to discuss it.
Language choice does have an effect on program robustness. That's just a fact. And it's also pretty indisputable that Python lacks many features that help to write robust code.
Pretending that isn't true is immature and unprofessional.
It has some pros of course - having a REPL is good for experimentation, and it has a great library ecosystem for example. But neither of those are particularly important for commercial medical devices.

I'm not exactly sure what you're asking here. Medical devices are often safety critical. They need to work extremely reliably. That's obvious; I think I must have misunderstood your question sorry.
I would like to as well, but that is very much not an option in most hardware projects at the time of writing of this comment. The ecosystem for these kinds of projects as a business in hardware is just too young to make it reliable enough to be shipping in a reasonable amount of time. Currently you really have very few choices in mainstream embedded programming for languages in a generic sense. You either work in c or c++, or you use micropython - and even micropython is young enough to invite some skepticism. No other ecosystem rivals these, though I do look forward to some promising commercial embedded Rust projects in the next few years.
