Why computer chips nanometers progress is gradual? Why can not the technology bump up to the lowest nm possible immediately since the concept and mechanisms of it is already known and studied

Partly what everyone here has said already – the technology takes time to develop and starting from square 1 makes more sense than starting at the final iteration.
Although, on the other hand, I’d say part of it is [“Planned Obsolesence.”](https://en.wikipedia.org/wiki/Planned_obsolescence)
Imagine you’re a company that makes computer chips – you can instantly make the smallest most compact most efficient chip possible – and then what?
After everyone who wants a chip purchases one – what drives sales beyond the slow trickle of replacements and late adopters?
IF, however, you design a chip that will become obsolete in 2 years – because you have an entire multi-decade plan for how you will scale down your chips over time, you can sell all of those chips… then 2 years later, they’re obsolete – your new chips are better… so you can sell all those chips to everyone who bought one before… rinse and repeat for a few decades and you’ve turned a one time profit into a long-term business model that will generate you billions.
