This is very impressive at 17, and her Github activity. So age definitely qualifies. We were fascinated with Mark Zuckerberg, or Bill Gates at their ages, so this isn't anything new. Doing anything remarkable at a young age is impressive and worthy to be noted.
This is a young person making strides in a hard field, and quite different from majority of peers at their age, but especially today with short attention spans, and TikTok, gaming, other distractions.
Another point is many high schools tend to coddle their students even for very little accomplishments. I was surprised by the attention one 16 yr old student got for making an interesting yet simple science explainer about the sleep cycle. She won the award in the Breakthrough challenge competition, got a 250K scholarship, and given feedback to the tune that she would cure cancer.
There's also a huge competitive gap between US High schools today on average, than many other countries. It would be great for the US system to challenge HS students again and reward real accomplishment.
