That’s interesting and it’s something I haven’t thought about. I’ve definitely been living in the world of “yeah, silicon fails every now and then, but it takes decades before any significant fraction dies of old age”. But of course that impression has been formed on stuff that’s decades old now and built on massively bigger processes.
The impression I get from this article is that if cutting-edge chips made in 2020 live beyond 2025 it’s only because the engineers are putting in a lot of work to prevent premature aging. So what happens when these processes trickle down to the point that every random el-cheapo manufacturer is using them? A lot more disposable electronics, maybe.
