Mmmm. Optimisers are software. There are two things I trust about software:
1: it has bugs
2: it is hateful
( see http://nick.hates-software.com/ and http://we.hates-software.com/ )
And it occurs to me that "Optimisers are written by humans. That's
just added another level of indirection, and hence potential for error"
To restate what I think was your original point some messages ago:
Yes, usually, hardware costs less than humans. But not always.
