So you are suggesting that a young AME would be better suited to be trained to introduce new type / generation A/C / with new EASA type licensing system.
That does not compute!
An AME is far better off learning on the job type experience before his / her first type.
There is more to learn than nuts & bolts.
The old blokes won’t be here forever so training will always be ongoing.
From time to time all training stops, how often has that happened,
only to open in a big hurry when, oops, all the licences are deserting, as they are now.
Its just another cycle.
The cycle always go full circle.
Seen it too many times now.
