This is a good idea. It gives experience a practical use and encourages people to stay alive instead of jumping in the ol' suicide pond whenever they get hungry. Seems no less industrial than turning sand and rocks and electricity into magic purple stuff that you can make into diamonds, or using a wooden bench, saw and a hammer to manufacture complex integrated circuits, etc. The only thing I would argue with is the ability to fly, which can only be briefly mastered before becoming one with pavement. Does not have to be a "brain machine" even, just some abstraction of the effect experience has on people at making them more proficient with stuff they do on a regular basis.
How about a comfy chair to sit in and collect your thoughts? After you think about the day you come to the realization that using your drill in some such way puts an inordinate strain on its motor, draining its batteries faster. A small lifestyle change could increase its battery life by some modest amount. Just an example. There are probably a million plausable sci-fi scenarios that don't involve recliners.
Just not sure if this could be coded at all. Would seemingly be like a potion whose effects do not wear off until you die.
Alternatively, I could see there being a Deadspace-esque upgrade table, that uses parts instead of experience to "enchant" tools. Would just be nice to give players an incentive to not die.
