This exchange reminds me of the debate I had with Jeff Atwood on whether or not servers should use ECC memory a decade ago. Jeff said no and I disagreed and said yes in https://danluu.com/why-ecc/.
At the time, there was one argument that could've, theoretically, been overturned by progress: Jeff argued that commodity non-ECC memory was becoming more reliable and was highly reliable. This was not true at the time, and it turns out this still isn't true a decade later.
