This is not a new, unknown or exaggerated issue.
Hypothetical No.1
You have a significant illness and a choice of three doctors. Dr Boomer who studied and received training in medicine roughly 30+ years ago, Dr X who studied and received training in medicine roughly 15-20 years ago or Dr Y who studied and received training in medicine in the past 10 years.
In the wake of universally recognised and accepted drops in University budgets, streamlining of courses and lowering qualification standards to previous generations of graduates I suspect most folks would prefer (when choice was available) either Dr Boomer or Dr X.
Hypothetical No.2
Through a series of circumstances you have been charged with various offences and facing a possible sentence of up to 25 years imprisonment. You have a choice of three barristers. Counsel Boomer who studied and received training in law roughly 30+ years ago, Counsel X who studied and received training in law roughly 15-20 years ago or Counsel Y who studied and received training in law (over the internet

) in the past 10 years.
In the wake of universally recognised and accepted drops in University budgets, streamlining of courses and lowering qualification standards to previous generations of graduates I suspect most folks would prefer (when choice was available) either Counsel Boomer or X.
