I'm not sure that task needs a humanoid robot, but the ability to grab and manipulate all those packages and recover from failures is pretty good
An industrial robot arm with air powered suction cups would do the trick... https://bostondynamics.com/products/stretch/ ...
... So the task they work best at is the task there is already cheaper better robots specialized for.
Like LLMs being used to pick values out of JSON objects when jq would do the job 1000x more efficiently.
This is what this whole field feels like right now. Let's spend lots of time and energy to create a humanoid robot to do the things humans already decided humans were inefficient at and solved with specialised tools.
Like people saying "oh it can wash my dishes for me". Well, I haven't washed dishes in years, there's a thing called a dishwasher which does one thing and does it well.
"Oh it can do the vacuuming". We have robot vacuums which already do that.
And if you needed it programmable, well an FPGA was still almost as general and far more efficient than a microprocessor.
Guess what won.
It's Moore's law that largely drove what you describe.
Moore's law only applies to semiconductors.
Gears, motors and copper wire are not going to get 10x faster/cheaper every 18 months or whatever.
10 years from now gears will cost more, they will cost what they cost now plus inflation.
I've literally heard super smart YC founders say they just assume some sort of "Moore's law for hardware" will magicallyake their idea workable next year.
Computing power gets, and will continue to get, cheaper every day. Hardware, gears, nuts, bolts, doesnt.
Once software is "done" (we all know software is never done) you can just copy it and distribute it. It is negligiblehow much it costs to do so.
Once hardware is done you have to manufacture each and every piece of hardware with the same care, detail and reliability as the first one. You can't just click copy.
Often times you have to completely redesign the product to go from low volume high cost manufacturing to high volume low cost. A hand made McLaren is very different than an F-150.
The two simply scale differently, by nature of their beasts.
It's not quite startrek replicator but much closer to that than the US view of manufacturing where you have your union guy sitting in front of the machine to pull the lever.
