Like, "we can only hope to make reliable those things we can understand". Sounds reasonable, how can you argue with that? But, in fact, this is quite common in engineering. A lot of engineering is making reliable things we don't understand!pic.twitter.com/lGzSb0m1bq
When I worked on flash mem (2001), I read the literature on how it worked. At the time, the exact physical mechanism by which some things happened wasn't understood. There were theories, but multiple theories were consistent with what was observed. But we can make flash reliable!
An example I particularly like: we're still not fully certain on why bicycles don't fall down. https://idisk-srv1.mpi-cbg.de/~diez/test.pdf
And to the extent that it's not reliable, we can describe when we expect it to be unreliable and what the odds are. Someone might argue that this is equivalent to "understanding", but that's your point, I think -- the talk is so vague it can mean whatever you want.
He has this idea that composing simple components is the way to make robust systems and that abstractions over complexity are worthless.Sounds reasonable, but we manage to build reliable chips even though the underlying physical mechanics we abstract over are tremendously complexpic.twitter.com/ESbBbYQKgB
