ramsrc makes a useful point about fluency ... doesn't matter whether we are talking about learning morse, touch typing, another language, or whatever .... until we get to the stage of bypassing the internalised translation process step, fluency, confidence, and speed cannot be obtained ..
As to whether we should all be umpteen wpm fluent in morse is a moot point .. but, having learnt it years ago and got to a basically comfortable competence, it does worry me just a little to see IFR pilots having to look up the dits and dahs on a chart to check the ident for a particular aid ..
