It is a terrible thing, and it is absolutely nothing like finding bugs.
Reproducibility is a core requirement of good science, and if we need to compare it to software engineering, the reproducibility crisis is like the adage "many eyes make all bugs shallow", when the assumption that there is many eyes even looking is often untrue. Most studies are never reproduced, but are held as true under the belief that if someone tried they could.
EDIT: You claimed that in an ideal world, 100% of experiments/studies would not be reproducible. This denotes a profound misunderstanding of the scientific process, or the whole basis of reproducibility. In an idea world, 100% of studies would be vetted through reproduction, and 100% of them would be reproducible. This is essentially the fundamental assumption of the scientific process.
No, I claimed that all scientist would have had the experience of not reproducing something. Because if they do it a lot, as part of a regular process then they will eventually find something that doesn't work because the original scientist didn't document a step correctly or misread the results or just got lucky due to random chance.
Just like all developers will eventually find a bug in code they code review. This is different from all code they review having bugs.
While the wording may be vague, they aren't talking about the experiences of a subset of researchers -- they are saying that of the experiments they tried to replicate, 2/3rds weren't reproduceable. That is terrible, and has absolutely nothing to do with finding bugs.
