I thought you must be wrong - $5K for a dumb arty round? But some googling indicates this is about right, and prices have even gone up since the Russian invasion.
I don't have real numbers for anything, but I tend to do analysis like the above quite often when evaluating business models. It's usually within a factor of 2x to 10x of being correct, so please don't take it as anything more than that: A typical round weighs around 40 kilos or 100lbs. For reference, from a quick web search, as commodities: - 100lbs of TNT would be around $500 - 100lbs of stainless steel is around $…
That's a great analysis. I didn't think about the sheer quantities of materials needed.

Of course, the details of how to actually implement something like this are way more complex than "just throw everything into a big neural net with images as the inputs and actuators as the output". You need to provide the right kind of guidance in order to learn a usable policy in any reasonable amount of time. A very recent development (which this work builds on) is the idea of "online adaptation". It essentially i…
I guess this is why evolution is taking unreasonable amounts of time.
From your perspective. In reality "amount of time" is quite abstract. Million years can still be "a blink" for an entity with different perception of it.

Ideally, the panacea to such nightmares is democracy. In practice, history shows that greedy people with power often don't understand anything other than force (sadly).
> Ideally, the panacea to such nightmares is democracy. Come on man, this is delusional. I want to believe it too but be realistic.
Idk, it really depends on how strong your affiliated lobby group is. The average voter competes against the Havard Kennedy or Oxford etc. graduate-led super PACs, lobby groups, whatever. So yes, it gets easier to believe "democracy" doesn't work or exist. However, lobby groups and elected officials wouldn't be a thing if we (society) didn't have the impetus, burden, or requirement to collectively believe (or have others do) that a thing such as democracy does exist. So if someone has a requirement to make you believe something, you have to ask why? In most cases you can acquire some kind of resolution using that.

The metrics they're using (2x its height for climbing a wall, 2x its length for crossing a gap) are weird and don't really relate to the same achievements for a traceur. 2x its height is really more like slightly over 1x its usable body for that maneuver (0.4m length, 0.51cm height of the climb). I agree, not extreme but still pretty impressive for a robot. We're not going to see them doing cat leaps any time soon ;)
Relative size of leaps doesn't seem to be a particularly useful metric for assessing the NN performance anyway, since in the absence of the human constraint of fear it's really limited only by the mechanics of its legs and its weight. More impressive would be adaptation to obstacles without clearly delineated edges, sticking landings on uneven/moving landing sites, and especially avoidance of landing sites which appe…
I'll extend 'avoidance of landing sites which appear incapable of supporting its weight properly' to 'avoidance of landing sites which are off-limits, including living things'
E.g. A sleeping dog that is motionless, a valuable item, wet concrete.
I suppose I'm going out-of-scope, though.

#166This all seemed a lot cooler before that Black Mirror episode, now every time I see a cool video like this, I get scared.

its actually hard for robots to compete with 10 year olds
But how amazing is it that this is even a thing to consider today
Well I was very conservative in choosing a healthy 10 year old as a point of comparison. A trained 10 year old can do a lot more. This guy was 7 at the time of filming: https://www.youtube.com/watch?v=1c__4ETI7aM
I'm not trying to diminish the accomplishment with respect to the state of the art of robotics, just bring some reality to the comparison against what humans are capable of.

What's the Black Mirror scenario?
General dystopian outcomes. After world powers harness robotic armies, revolts will no longer be possible and citizens will be permanently enslaved and must succumb to whatever oppressions are put on them.
Sometimes when I watch videos like this I really wonder what the future is supposed to look like , heavily regulated I guess? All out chaos? Imagine what a criminal organization could do with a bunch of robots that are this agile? It's hard to imagine.
Personally,I think we'll get really good at killing robots and they'll get better at killing people (military).
