All the ‘experts’ need to try seeing things from another person’s perspective. The video was a bit of reductio ad absurdum, the main problem I experience isn’t a lack of understanding from non-technical people, but a lack of flexible thinking, and intellectual bullying from ‘experts’.
It’s fine being an expert, but if you can’t explain things to people then you need to change your personal style. Likewise, it’s all very well demonstrating your expertise through highlighting the faults in any solution, but if you can’t collaboratively think around the problem and evaluate alternatives then you’re no good either.
Some people on this thread appear to have hindered their own career/progress through being unable to moderate their own behaviours to be more compatible with others – you can definitely get useful training for this. I thought it was useless until I did some courses which identified exactly what I did wrong in this sort of interaction, and why my actions caused negative reactions in people with a different style/approach, was quite an epiphany even though I’d always thought I was quite self aware.
