The problem is that you're not only putting yourself at risk when you don't update.

You're putting everyone who you've talked to at risk. I don't know about you, but I prefer not having to worry about whether I'm communicating with someone whose installation can easily be pwned by any halfway incompetent attacker.

This has 100% been my experience, even with in-person shopping.

You ask for an Arduino, and the follow up question is: 'genuine or generic?'.

I don't think the Arduino trademark is that valuable, it's already well underway genericization.

The NPU is somewhat usable on RK3588(S(2)) boards, as long as the kernel you’re using is recent enough to have the latest NPU driver.

For a quick bring-up and implementation, take a look at this repo: https://github.com/Pelochus/ezrknpu

I have a Radxa Rock 5C (on Armbian) and it runs various models rather well. Trying to convert models is kind of a pain, though, so watch out.
