My point exactly. Its not 1000 hours and 1000 hours. Its 1000 hours and 1,000,000 hours. If we could program a complex robot like spot to do a highly complex task like walk a dog safely on an open ended "real world" in 1000 hours there are lots of other things we would do first (package delivery comes to mind). We're just not there. We have the hardware, but not the software infrastructure to apply them as is being expected here.
