Short coming as feature

I visited Kyoto lately and during my research for my trip, I learnt about Kailado, who specialized in making container for tea leaf from copper, brass and stainless steel.

It required some skillful hand to make those perfectly shaped, air tight container but one "feature" they highlight is, the container will change in color over time.

The change in color is due to the material getting anodized, in layman term, it gets rusted.

Some will treat this as a short coming but it is indeed packaged as a feature, where each identical item will become different, with our own personality. Thinking further, it is a natural occurrence. Instead of getting rid of it, we embrace it.

But how does this translate to our technology?

System is not likely to be perfect, but the main function should be very well polished and user will find their way in using it.
