nooooo!!!! but then there wouldnt be the fun of lusting over bigger better lenses

I certainly hope not!!! But I did a lot of research before I started up LensesForHire and, whilst there are a number of potential technological disruptions on the horizon, this isn't one of them.
Two main reasons.
1. There's a limit to how small sensor pixels can be. Pixels are essentially devices for counting photons, and you need enough photons landing on each pixel to be able to discriminate between different tones. Make the pixels small enough, and sooner or later that won't work. (And we're surprisingly close to that point alreeady.)
2. A mega-crop from a 10mm lens doesn't look like a picture from a 500mm lens. The depth of field characteristics, for example, will be totally different.

Ah well, I am pleased in a way, but what if there is some quantum leap in technology rather than just reaching the limits of current technology.... Maybe some device that can catch a vast amount of visual data and process it. Like the human eye but much better!

today maybe but who knows what the future may bring.
There was once a time when man thought flying could never be done, we once laughed at the thought of having a phone you could carry around, record players where the size of dinner plates and they even once said the camera never lies.....all have changed to this day so NEVER say NEVER :nono:
Theres nothing in physics which says you can't fly, its an engineering problem. As stewart has explained, this idea isn't possible.
If you wan't to look it up further, google nyquist theorem and diffraction.

I know. It will bring exactly the same restriction. As sidxms says correctly, this is fundamental physics. It's not going to change.

my vision is we all have camera's in our heads and we blink to take pictures
That would be so interesting wouldn't it .. and very wide angle blur with a sharp bit in the middle I reckon.
