  • Ukraine is a major global food supplier. The war has directly impacted food prices. And if Russia succeeds, it will only encourage more conflict of this kind. And that’s ignoring the possibility that this will escalate into an even larger conflict because Putin decides that NATO’s resolve is weak enough that article 5 is no longer a plausible threat.

    Also, that stupid argument applies just as much to funding schools, cancer research, fighting climate change and basically all other functions of government that serve the public good. We should do more to address economic issues, but that doesn’t mean we should stop doing everything else.


  • My dad used to tell me “It’s a lot harder to carpet the world than it is to wear shoes.”

    Ambitious redesigns of existing infrastructure are neat, but they are rarely more efficient or practical. Especially when you are overengineering to solve an issue that’s already been dealt with. A self cleaning room requires a lot of additional hardware, all of which has to be designed, built and installed, and has to be powered and run by software that needs to be programmed. It also needs to be maintained, and depending on how it’s cleaning things, it may also be dangerous, or at least capable of damaging property (ever have a motion activated light turnoff while in a bathroom stall? now imagine it triggers steam jets). Not to mention the potential hazards of water damage on a room if anything goes wrong.

    Or, you can buy a mop for 0.1% of the price.

    Humanoid robots can escape this problem because versatility adds value. The upfront cost may be tens of thousands of dollars, but for that price you’re getting something that solves many, many problems. They can potentially go from task to task, filling a multitude of roles, and ideally with minimal down time.

    It also helps that we can use existing processes to train them. They can observe human workers performing a task, attempt to replicate that task, and use feedback to improve. And that’s critical because the hardware is the easier part, it’s software that’s the real challenge.


  • It’s easier to build a specialized robot for one task than to create a general purpose robot to handle that task. However, as the technology matures, I think it becomes much more practical to create a general purpose robot that’s capable of performing millions of tasks than to create millions of different specialized robots. Not only is that far less to design, source parts for, build and maintain, but it also makes it much easier to repurpose them as needs change. The same basic design can potentially be used for factory work, household chores, new construction, search and rescue operations, food service, vehicle maintenance, mining, caring for kids/elderly/pets, building and maintaining other robots, etc. We’re not there yet, but that’s where this kind of technology could potentially take us.

    The advantage of a mostly humanoid robot is that it’s versatile and can use existing solutions built for people. Yes, you could replace the legs with wheels or treads, and you’d probably be just fine for most functions with a Johnny 5 type design, but there will still be exceptions. Being able to climb up or down a ladder for example means that you don’t have to engineer a solution to deal with getting onto a roof or down into a tunnel system. We’ve already spent thousands of years solving those problems for humans.
