The fact is that pilots are no longer trained for spin recovery or for other recovery situations so maybe we need more pilot assist methods to compensate for partially trained pilots ???
They are not partially trained pilots, they are properly trained pilots. Spin recovery is no longer in the PPL syllabus in the US or Europe because it's no longer the 1930s. When training causes more accidents than it prevents, as was the case with spin recovery training, then you rightly stop the training.
The logic is so obvious. Look at Gehghis comment on BRS. When an airplane is being flight tested, a BRS is fitted to assist recovery from difficult situations like spins. Does this mean test pilots are partially trainined? No. It means a pilot assist device is generally a good thing to mitigate risks.
