so a woman tradie (electrician, former military engineer) i have a take on bean guy. its a classic of dude bro dad/supervisor setting his daughter or any other woman up to fail while pretending to be supportive but really doing it for the lols and to prove his own superiority
first off, if your kid can't open a can, that's on you. its not like when some teen shows up to work and can't operate a broom (ive seen this). this is your kid. any basic lifeskill gaps they have are your own fault.
secondly, if your kid lacks "mechanical aptitute" that is also on you. mechanical aptitute, like most other skills, is learned through experience and practice. (see @johnmighton 's book "the myth of ability" for a detailed examination of this)
(when I joined the military as an inexperienced 18 year old, I was told I had no mechanical aptitude (despite scoring great on written aptitute tests). when I started as an electrical apprentice a decade later, I was told I had great aptitude. it was my experience.)
one thing that really undermines mechanical ability is being repeatedly told that you suck. bean guy told us all her daughter sucks and has no aptitude, i bet he's told her that to her face too. this undermines her ability to develop those skills
also being hungry or tired or frustrated undermines your ability to solve spacial or mechanical puzzles. this kids totally reasonable expectation of being fed by fed by her father would also cause anger which is not unjustified
anger also undermines your ability to solve complex spatial puzzles. anger makes you want to hit things with a hammer. in construction sometimes this does solve the problem. a hammer and anger may have been an out of the box solution to the bean/can problem
however bean guy says that his daughter wanted a hammer and he didnt give it to her. this is honestly the solution that being hungry and angry provides (and may have worked you can for sure open a can with hammer and a screwdriver as @nikostratis pointed out earlier today)
but actually figuring out complex mechanical/spatial problems requires some calm, which is less likely to happen when hungry and angry. this is why getting poor kids breakfast helps their grades.
theres this thing that happens in the trades (98% male) where some dude pretends to be helpful but really just undermines your confidence while all the while seeming to be a good guy who is helping out
when the woman or other minority inevitably fails giving this type of passive agressive undermining "help" its seen as proof that women shouldn't be in trades or that this particular woman has no aptitude. ix they get angry its becuase they have a "bad attitude"
if someone the woman (or other minority) succeeds despite being constantly undermined and belittled and given tasks that either too complex or too simple, its because our Great Hero Dude has been such a magnanimous and amazing teacher
in the end perhaps your daughter learns some skills. but the hidden curriculum is that you hate her and her gender and you think she sucks. you've set her up to fail, and also to take credit if she succeeds. bean guy wins both ways.
also bean guys kid is 9 years old. I have a 8 year old. she sometimes needs help with her zipper if it's a difficult zipper. she is learning how to braid hair. she recently taught herself how to cut up a tomato with a knife becuase she wanted a tomato sandwich at 11 pm
the tomato/knife task is age appropriate self feeding task for an 8 or 9 year old. she has also seen me use a knife many times, has handled one, and humans are maybe genetically programmed to be knife users since homo erectus. can openers are less intuitive.
