I'm sure you meant silicon not silicone (silicone is used for breast implants

)
IMO a poor photo cannot be turned into a master-piece by digital manipulation. e.g. harsh light, soft focus, motion blur, bad head angle, bad wing position, bird flying away from the viewer, bad pose etc. are often the main reasons a photo is not appealing to the majority of viewers. None of these flaws can be fixed by post processing.
I agree and these and this are equally true for film photography
You have to get it right in camera and then use post processing (e.g. noise removal, removing color cast, adjust exposure, cropping etc.) to present your photo in a natural, pleasing way, that conveys your message to the viewer in the most effective manner.
