Wait. So, a high school student interned at Nvidia?
I was a huge dumbass and turned them down.
That does count as broader access, methinks. So, I suspect you're right. There are many, many sources of inexpensive education. I don't know if that would, statistically speaking, increase the actual numbers/percentages - but if it doesn't, it would almost certainly enable them to go further.
Ever wonder what it'd be like to have had access to this stuff when you were younger? Personal computers didn't arrive until I was an adult.
Anyhow, kudos on the kids. That is impressive and certainly better than I can do.
