When you read the fine print you find out that’s for a 2D simulation of a robot arm that isn’t moving. Real world results from coworkers showed it being about 10x slower than Drake in meaningful sims.

Some cold water on the claims here: <a href="https:&#x2F;&#x2F;open.substack.com&#x2F;pub&#x2F;stoneztao&#x2F;p&#x2F;the-new-hyped-genesis-simulator-is" rel="nofollow">https:&#x2F;&#x2F;open.substack.com&#x2F;pub&#x2F;stoneztao&#x2F;p&#x2F;the-new-hyped-gene...</a><p>tl;dr: The way they&#x27;re able to claim a massive speedup is by simulating much simpler scenarios than those being simulated by other systems.

I believe this is how some robot vacuum companies perfected their algorithms 10-15 years ago; basically simulating inputs to the software from LIDAR&#x2F;bump sensors and figuring out how to avoid getting the robot &quot;stuck&quot; in your living room.

There are self driving car companies doing the same kind of training. I know because I spoke to an employee who works at a startup that provides this type of software as a service.

OT, but that&#x27;s the second time this month I&#x27;m encountering TLS issues with <i>arstechnica.com</i>... seems to be some mixup with the domains for <i>intuit.com</i>.

Sim is how we get to ASI. But physics is hard. In the meantime is anyone hiring a bunch of people to wear motion cap suit, cameras and mics 24x7?

Not enough comments, is this the ushering of a new era of robotics? Is everybody going to be replaced now?

This piece was less about robotics and more about creating cool scenery.

Kinda nitpicking, but why is &quot;SIM&quot; allcaps here but not on the source article? It&#x27;s a &quot;sim&quot; (short for &quot;simulator&quot;), not a SIM card for a cellular phone :&#x27;D
