Hey, I am retired myself, so some time to play with stuff.
There is such a thing as 'experience', I have seen thousands and thousands circuits,
I have had to repair those too at times, I have a pretty good feel what fails and what does not.
I did both design and repair of stuff, including very high end stuff from media to mil to science.
To 'prove' something works there is only reality.

I do not give a <...> if you (mathematically) prove say a wormhole to me (people do),
but if I can buy it and travel through it and can come back to tell,
I won't ask my money back.

Hiring interviews is always interesting, there are often other forces than tech at work,
say discrimination, personal preferences, friends of somebody... politics.
Then, simple relay driver one transistor, forget the diode...
I had a repair shop, let them repair a set.

In show business there is 'the show must go on' you have to know the stuff in depth,
enough to improvise and invent on the spot or fault find in 1 minute in equipment most here never even 
could fathom in 10 years of study.
And, with electronics, things are always in motion, you study forever,
[LT]spice is just a small niche in it all, toy basically.
The human neural net configuration and weights is where it really is, that is why it is different for everybody.
Until the day we can transfer that neural net configuration and weights, teh new kids on teh block
will have to start again from scratch.
But now they chase Pokemon and want Python...

OK.
And Dinos are no more either.
You gotta give it to the last Dino, if he had a good time he was doing OK.
