agesplaining noun [U]
/ˈeɪdʒ.spleɪn.ɪŋ/
the act of explaining something to someone in a way that suggests that they are stupid; used when a young person explains something to an older person that they already understand
You may have heard of mansplaining, when a man explains something to a woman in a way that’s regarded as condescending or patronising. But how about “agesplaining”? Forty-four per cent of the men and women who said they had experienced agesplaining said it left them “feeling older than they are”. Seventeen per cent said it rocked their confidence, while the same percentage said it had “contributed to a loss of self-identity”.

ageotype noun [C]
UK /ˈeɪdʒ.əʊ.taɪp/ US /ˈeɪdʒ.oʊ.taɪp/
a category of changes that occur in a particular person’s body as they age, which is distinct from the way people in other categories age
Now, studies have revealed that we tend to age down one of four different pathways. This is your “ageotype” – the principal way in which you, personally, are ageing. The bad news is that the oldest part of your body may be dragging the rest of it down. The good news is that by working out your ageotype, you might be able to target it to live healthier for longer.

agetech noun [U]

the business of using technology to offer services that help old people
The market for agetech could grow to $2 trillion, according to an estimate by 4Gen Ventures, a VC agetech fund. Technologies for older generations include smart appliances, in-home connected devices, wearable robotics and digital care companions. The few corporates that have invested in agetech include Japanese electronics maker Edion, which launched a $63m CVC fund in June this year to invest in age-related technologies that address the shifting demographics of its consumer base.

I would humbly suggest “bossplaining” to be added to Cambridge English dictionary, as another extension from the well-known “mansplaining”
Or perhaps “managersplaining”?
I think the definition of “mansplaining” misses the deeper meaning of the word. It seems to me that “mansplaining” is when a man explains to a woman something, an experience, a situation or a condition that only women can experience. The word also focuses on the social dominance of the aggressor, the man in a patriarchal society. In that sense, the word should be something like “youngsplaining” instead of the more neutral “agesplaining”.
