So this is a decent article overall but it's missing a key part of the discussion which is "why?".

Gifted children don't just benefit from instruction catered to them, they often need it and the absence of it can be actively damaging. Such children experience the world differently from normal people just by simple function of being less normal.

I attended an academically selective high school, yet I was the "nerd" at the nerd school, I went on to do a CS degree and again, I was the nerd in what could be considered the nerd course at arguably the nerdiest university. Both institutions are probably considered best of breed in my country. So I would say I'm probably pretty qualified to speak on what it's like being "gifted".

The sad reality is that gifted often isn't accompanied by success, at-least not in the outright sense that many think about it and that is because said gifts many times come with costs. Not always, some have social skills, athleticism and are highly functioning. However in most cases extreme intellect also comes with being a social outcast and not sharing in the same hobbies or worse yet not even relating on the same level with similarly aged peers. Turns out increased intellect also generally comes with accelerated maturity and differing interests to those less mature, who would have known!

So how does this factor into schooling? (prepare for gross generalisations). Well first of all a school is generally one of the worst places on the planet for a gifted child, especially for their favourite hobby - learning. It's full of kids that don't give a rats ass about learning anything, adults that are tasked with trying to make these other children do something they don't want to do/play babysitter and a ton of arbitrary rules. Teachers don't have time for gifted children, they are struggling to manage a classroom of clowns and/or try keep the laggards up to a passable standard. Which is another problem, as a society we seem to care much much more about ensuring special needs children aren't left behind than we are that our best and brightest are able to achieve their potential. Maybe we just think "hey they are smart, they will work it out" (oftentimes we do) but I really don't think people are seeing how "gifted" kids struggle.

I tend to quote "gifted" for this very reason. Everyone I know that falls into the category has emotional scars for one reason or another, most of which borne early in life during school and endure their entire life. So yeah, we are smart but we are also likely on the spectrum, even when social difficulties are mild our interests shoehorn us into isolation that further increases social development problems because of how cruel children are.

The best thing my parents/educators did for me was to realize the system isn't built for people like us and accelerate me 2 grades (at 2 different times, not a single massive jump) so I could at least get out of it as soon as possible. I didn't do as well in school as I should have, I was branded a trouble maker, suspended constantly and even expelled twice (well asked to leave). I didn't even do anything that bad - I just wasn't wanted there.

University was better but I was woefully in-equipped to actually do well. Not for intellectual reasons, just beaten down self-esteem, clinical depression, etc. I made life long friends however so it really doesn't matter in the end. If anything finally making it to university saved my life because there was finally a high enough concentration of people like me to make real friends.

These days I'm "very successful" by societies metrics. Well traveled, wealthy, own my own place, have a great relationship, healthy, all of that. So I guess there is some truth to the fact that "we will work it out".

But the experience has made it really hard to stomach the idea of having my own children.
What if they turn out like me?
What if they have to endure the depression and pain I did? (and still battle with)
I don't know if I could do that.
I'm not strong like my parents are, it would break me to see my child go through that knowing that the system is stacked against them.

So while everything in this article sounds helpful I think the most helpful thing would be to try address the actual dynamic of schools from a social and emotional perspective for gifted children. That alone would make the biggest difference in their outcomes.
