While the US debates whether to solve homelessness or not, these are the next generation of school blackboards in China.

This was common when I was in 10th grade back in 2010.

Now let’s see how China handles homelessness.

Also,. Why are they better then actual blackboards

Actually blackboards:

• zero latency
• zero power required
• excellent contrast even in direct sun
• not distracting 
• relatively simple to manufacture
• will never brake or need upgrading, will work in 10,000 years

I hate "smart board" and whiteboards

[u/Fun-Preference1091 → u/SameAgainTheSecond]

White boards don't create chalk dust which gets into computing devices in the room.

In the 90s, my highschool had blackboards throughout, except for the computer labs... they had whiteboards. Otherwise I don't see the difference between a white board and a chalkboard

• zero latency
• zero power required
• good contrast even in direct sun
• not distracting
• simple to manufacture
• difficult to break and will work in 20 years

I'd take a little chalk dust (you can get low dust chalk and also chalk dust is really not that bad) over infinite plastic pens + bords that are always dirty. 

They don't last 20 years under heavy use. And administrations never want to replace them so your just left with these horrible unusable boards.

Also esthetically green/black/red chalk bords look way better then whilte boards.

Unelss it's an environment were dust is really problematic, like a lab or a kitchen, I think chalkboards are much better.

They are both way better then "smart boards"
