       | One comment on what the article says:
       | 
       | > If this were actual code review the correct comment would be
       | something like "this [piece] hasn't been used for years, it
       | should be deleted". But this is something in physical space, and
       | there would be arguments that removing it (them) means the route
       | has changed, thus times are no longer comparable.
       | 
       | Hmm, I think the correct analogy is rather a benchmark. Like code
       | in a benchmarking tool or test, the whole climbing course does
       | not serve any purpose, any actual goal, except to be completed as
       | fast as possible.
       | 
       | You wouldn't say "these instructions should be deleted because
       | branch prediction and speculative execution in recent years have
       | made it so that total cycle count is the same without them", for
       | the reason stated ultimately after in the article already: That
       | may not have been true in the past, and may change again in the
       | future.
