The extreme difficulty of scaling production of new technology is not well understood. It’s 1000% to 10,000% harder than making a few prototypes. The machine that makes the machine is vastly harder than the machine itself.

Prototypes are a piece of cake, but high volume production of a new technology is extremely hard. Takes much longer than people think to climb the production S-curve. I can’t emphasize enough that production is by *far* the hard part.

Btw, just want to express a word of appreciation for the hard work of the Tesla Gigafactory team. Reason I camped on the roof was because it was less time than driving to a hotel room in Reno. Production hell, ~8th circle …

Many movies exist about a lone inventor in a garage having a eureka moment, but almost none about manufacturing, so it’s underappreciated by the public.

Compared to the insane pain of reaching high-volume, positive-margin production, prototypes are a piece of cake.

There's just not really a movie about that, but there should be.

The manufacturing is somewhere between 100 and a thousand times harder than making a prototype.

Oct 31, 2023 · Joe Rogan Experience #2054

You could say, to first approximation, there are 10,000 things that have to go right, at least, for production to work.

I think currently a factory is underrated and design is overrated.
