I actually agree with 'QM/EM based life'. My current thinking goes as following..

- Intelligent life develops superfast AI

- - then develops even more advanced quantum version of it.

- Life slowly starts augmenting its meatspace with advanced replicable machinery

- Eventually everything starts becoming very predictable so it start absorbing the advanced AI in our minds, which slowly becomes our essence (assuming consciousness is 'computable' ie.. not some penrose-esq orchestrated reduction)

- It then builds a hypercomputer operating at very close to max efficiency and start harvesting all matter/stars to sustain it & migrates to it.

there is another path where just like light currently exists as an EM wave packet we discover other stable forms and migrate to that.

of course this does not means the pervious iterations of life do not continue to exist, just that they become increasingly irrelevant.
