         | Even wheeled robots can climb stairs with the right platform, I
         | think that's still cheaper, less complex and error prone.
         | 
         | But from a pragmatic perspective, it sounds like a very
         | reasonable tradeoff to simply not support stair climbing. It's
         | not like that thing is gonna walk itself from the workshop to
         | the target area. If someone has to carry it anyway, they could
         | conceivably carry it down some stairs while at it.
         | 
         | (I'm a rather incompetent hobbyist when it comes to robotics,
         | but I've been researching locomotion quite a bit and find a
         | wheeled platform to be a good choice even in the forest
         | environments I focus on. Guess it's just not exciting enough.)

           | 1. Stair climbing isn't just about movement from top to

           | Cleaning litter on the stairs isn't accomplished by carrying
           | the robot down the stairs.
           | 
           | 2. Why do you believe the robot will always have a minder?
           | The objective very much would be setting these off from a
           | central location and covering a whole neighborhood or city.

             | If the point is to clean beaches and that's it, I think my

             | 
             | If the point is to _start_ with beaches and to then use the
             | same platform to clean up all kinds of yet to be determined
             | areas, a quadruped might indeed be one of the few viable
             | options. Wheeled robots can climb stairs with the right

             | terrain the way quadrupeds can.
             | 
             | Personally, when designing robots, I have very clear tasks

           | try to lose weight the 'hard' way. Literal blood sweat and
           | tears. Statistically, those interventions don't work well in
           | the long term. Plenty of the morally unimpeachable suffer
           | from weight issues. Clearly there is a physiological
           | component as well. This medication treats it.
           | 
           | Is it also a moral failing to take a Tylenol to treat a
           | hangover headache instead of suffering through the pain until
           | it goes away? Maybe surgery patients should just tough it
           | out, without anesthesia like they used to in the 1800s
           | instead of taking the easy way out?
           | 
           | People are treated for 'self-inflicted' physical issues

               | What you aren't grasping is that actual experts don't see
               | it this way. The use of Semaglutide points to the fact
               | that obesity is caused, at least in part, by a hormonal

               | still don't understand why so many people in some areas
               | are affected. Actual scientists have done controlled
               | studies and found that culturally similar people in
               | different geographies have wildly varying rates of
               | obesity. We live in a culture, where (as you have proven)
               | people will openly judge, insult and shame strangers for
               | being fat. Being fat isn't culturally accepted anywhere
               | (maybe a few isolated cultures are the exception). Nobody
               | wants to be fat. There is a multi-billion dollar industry
               | that serves people doing everything they can to NOT be

               | is not a moral failing.
               | 
               | Its like telling depressed people to cheer up. It doesn't

         | Unbleached hemp cigarette filters exist but only for slims?

         | Same with the highly publicized "man cleans up _____ and
