Not fit for the job.
I say this because I have first hand knowledge of how my own eyes gloss over and people 'loose me' when they talk of the innards of ADSB and other electrical gadgetry. It is beyond me why a pilot for another example needs to know how the constant speed propeller is made, assembled, tested and 'doctored' to its final specifications. As in PNG, the throttle is simple a gadget that 'pushemhegopullemhestop'. (not sure if I got that right but you get my drift). When you go into too much detail our 'fuzzywuzzie' mates just look for the next cargo cult party.
When saying I believe Truss is not fit for the job, I don't mean to be as offensive as it sounds, but simply he does not have the technical knowledge to get his head around some of the problems, so... he hands it over to his 'advisor' who is supposed to be knowledgeable in these things.
This is the 'Nigerian' in the woodpile I believe, and needs to prove to us all his knowledge of the 'problems' and he should expose and be transparent enough to show us his pedigree.
Truss obviously, is led by him.
But I was wrong once before.
