Is the academic system reaching a point where the scientific advancements are becoming too complicated and expensive such that it will no longer be possible to churn out the same numbers of PHDs? How will the academic community respond if such a point is reached?

Given that to get your phd, you have to expand science or knowledge somewhat, which means that the next phd student will have to have slightly more work to advance it and so on.  From what I understand, phd students are taking longer and longer to complete their studies, but the economy still needs them for education and work.  What happens if there is no longer enough phds to fulfil societies needs?  

I imagine some fields this won't matter, but in sciences and math, it would be worse.

Trust me, there are far far more PhDs still being churned out than open positions in academia. Just ask a professor or hiring manager how many applications they get for an open tenure-track position

Meanwhile, you don't (edit: ~~even~~ necessarily) need a PhD to get a job in industry...
