23yo claiming from "their own experience" that 15yo is
emotionally and intellectually formatted person is interesting.
Dear friend, unless you're seriously ill, health-care worker or a soldier, you ain't seen, felt, experienced ANYTHING yet, believe me. You don't know what it's like to get up every day just to spend another day in pain in your back, stomach or legs due to overtraining as a child. You don't know how it's to not be able to use a bathroom by yourself due to coaching mistake. You don't know how it's to live with screws in your spine, legs, arms in need of daily massages, anti-inflammatory drugs or medical assistance placed inside your body due to overtraining or injuries in youth.
Do you think, at 20yo, Elena Mukhina was intellectually and emotionally prepared for how her life was going to change?

Do you really think 15yo kid is?
15 year old is a 100% still a kid. a 23 year old saying 15 year-old is not a kid is a little funny, since 23 year olds in general haven't had much life experience yet to speak on topic whether or not 15 year olds are children or not.
However you are mixing things up here. I think Orlov did not mean that 15 year olds are responsible adults, who should be able to make their own life decisions,
but spoke about 15 year old's maturity as a performer, and that some 15 year olds can perform without any less maturity compared to 20-23 year old skaters, which is indeed possible.
Some 15-16 year olds do indeed have some performance factor that
some 20 year olds lack.
Some child actors have more performer talent and show better performances than
some adult actors.
Should I say, Evgenia Medvedeva at 15 could perform better than someone like Ksenia Makarova (once a russian national champion) at the age of 20.
This has no relation to whether or not 15 year old are capable or should be capable of handling important issues regarding their life and health, this should be handled by their parents.
Mukhina however is also not really a good example here.
Mukhina have not met a coach, but a person who essentially tortured and abused her and ruined her life.
Mukhina was not
just 'overtrained'.
Her coach literally got her out from hospital in her neck brace, despite doctors' protests and made her train, which instantly led to her getting paralyzed.
Another factor that played a part was that she basically was an orphan, her grandmother did not actively participate in her life,
which essentially allowed her coach to abuse her.
After she got paralyzed, she said that she's happy that she can finally be free from constant demands of her coach, which is quite telling that this is not a simple 'overtraining' issue.
That's a very extreme example, and there's a difference between a strict but reasonable coach and an abusive and cruel one, who sucked out all of the joy of life and sports for a kid.
