I don't think the academy is failing any more than is the historical norm. The collapsing cultural norms are not centuries old, they are a product of the academic boom of the latter half of the twentieth century, where the first world (and certainly America) was more or less peaceful, the population was sharply rising, and access to and demand for higher education was exploding. The academic norms of the 1980s would be unrecognisable to an academic of the 1920s, yet I claim that both academics are part of a longstanding lineage of people working towards a common endeavour.

And the reproducibility crisis is not an example of decline. It's not like social science used to be reproducible then stopped. It's that for the first time in history, we've realised that things are bad, and now we're (slowly) starting to do good science. The reproducibility crisis is an example of improvement!
