The effects of this are going to massive and huge in 10 years.
All those unfortunate children will be introduced to the toxic, horrid internet.
They'll be addicted, have no attention span, have their own data used against them to exploit and track them, and end up with their political system reeling under manipulative AI and generic bots.
Far better to just give them books for their educarional system, and leave the evil Internet out of it.
What you describe at its worst is still better than the exploitation many of the children in the Philippines endure today by westerners. Hopefully, being able to communicate on the 'evil Internet', the rest of the world, like you, can truly understand what they endure.
This sort of arrogance where suddenly everyone remembers all reasons why some technology is bad once the "poor masses" get it (while they themselves had the technology for years), is hypocritical and frustrating.
The reality is that getting online makes a massive difference for someone in some remote poor area. Not just in terms of education but also economically.
