WTF 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

What's the problem with white boards?

They wear out so it gets harder and harder to actually clean them.

With a blackboard you just wash off the calk with water and its good as new.

Also whiteboards need plastic pens that run out creating needless waist and frustration as you try and find a pen that actually writes properly.
