With most tech we reach law of diminishing returns. That is sure, there is still a variation, but very little:

- the best laptop/phone/tv in the world doesn’t offer mich more than the most affordable

- you can get for free a pen novadays that is almost as good at writing as the most expensive pens in the world (before BIC, in 1920s, pens were a luxury good reserved for wall street)

- toilets, washing mashines, heating systems and beds in the poorest homes are not very far off from the expensive homes (in EU at least)

- flying/travel is similar

- computer games and entertainment, and software in general

The more we remove human work from the loop, the more democratised and scalable the technology becomes.
