I came across this news recently on the Internet and I was really amazed, excited and hopeful as well, those siblings are vert smart and behave very maturely in the for their age, something not very many adults are involved in, this little kids are able to handle effortlessly, congrats to them, their parent must be very proud.
It's actually their parents have thought and led them to this.
If it's not for the father of these two then they won't be able to make their rigs. But true to that their parent are totally proud of them because at their young age, they can now make money.
And it's the education through this technology gave them an advantage than the other kids. We just hope that their childhood aren't compromised.
