ROBOT LIFEGUARD PROBLEM

Robot lifeguard … at pools.

So if your kid falls in, they don’t drown if you’re not around.

(wake me when that happens)

(it seems like a trivial problem – or is it?)

Think about the swimming pool scene in the movie “Caddyshack” (1980), how does a robot navigate that scenario? – lots of kids screaming, superficially they seem like they’re drowning.

A heuristic database might include a rule that says: “must be below the surface, this long …” … That’s a simple rule. As long as the robot can determine if a child has been below the surface too long – but this too gets harder as you add children to the pool, or other objects.

It’s not a non-trivial problem.

SPARKS was RIGHT!

In the YEAR 2199 …

… not everything was fine …

… the Earth was almost dust …

… the land was a bust …

… Gamilon planet bombs have turned our world to RUST …

… BUT WAS THERE HOPE?

General Lysis … shit posting about the STAR FORCE …

… this is where it gets kind of rapey …

… we learn some truth about Japanese culture …

… women are disposable things …

… women are like potato chips …

Isn’t that RIGHT, SPARKS?!?

What did we learn:

  1. MARS is 1,000 light years away – and it snows there.
  2. Pluto has amoeba creatures or protozoa living on it.
  3. Towards the end of SEASON 1, shit goes downhill …
  4. Japanese culture is kind of rapey. Sort of into a LOT of having sex with unconscious women … damsels in distress …
  5. Humans are kind of rapey …
  6. There are no heroes …
  7. All navy guys are kind of rapey … US … Chinese … British … Turkish … rapey
  8. The ARGO is a giant rape cannon … wave motion gun? – what kind of porn-hub James Deen rapey’ness is that? The Desslok gun? Come on … hide your L’s better …
  9. SPARKS was RIGHT!
