>Phones don't have optical zoom - Yet.I highly doubt phones ever getting optical zoom just for size reasons. That being said there are some rumors of the new iphone having 3 lenses with different focal lengths (wide, tele, super tele?) and that seems to be way more cost effective in the long run.
>Galaxy S9 has a variable aperture camera.But does it affect the image quality at all? (ie: dof, sharpness, etc.) I think I already know the answer anyway.
>everyone is dropping insane amount of money on their developmentHonestly all people want from a cell phone camera is good low light performance which is why all sensors are stacked and backlit now, thanks to software optimized editing and filters everything (like bokeh and focus) can be handled by the processor. I imagine future phone cameras looking like these "Light" cameras.
