How can I describe something that is easy to improve?

Say I have a person who is fond of change/prone to progress or a technology that is designed to be easily changed and improved. What is an adjective I can use to describe both or either one of them?

I am trying list the advantages of synthetic organisms and want to express that they can easily improve themselves over a short period of time, as opposed to humans.

Usage:

The key advantages of synthetic organisms are lack of emotions, apathy, ruthless pragmatism, exponential learning and [the fact that they are easy to improve]

I believe you example requires a noun rather than an adjective as you requested:

The key advantages of synthetic organisms are lack of emotions, apathy, ruthless pragmatism, exponential learning and updatability.

updatability

Two ideas have to be combined in this adjective, the possibility of being improved and the easiness of any improvement; it is not likely that such a term exists. However a combination of words is possible.

(vocabulary) meliorative adjective tending to ameliorate
synonyms: ameliorating, ameliorative, amelioratory

• The key advantages of synthetic organisms are lack of emotions, apathy, ruthless pragmatism, exponential learning and their being readily meliorative.
