Think of our GPU as a robot arm that paints cars. We own a car factory, and we bought the robot arm (GPU) from an agency that also sent a trained operator (the device driver) along with it. But a few years later, various companies start making robot arms that can both paint and weld. We want our robot arm to do that, too. But the operator doesn't know anything about welding, so we can't even explain to them what we want the robot arm to do. | Think of our GPU as a robot arm that paints cars.

Someone sat down and figured out how to work the robot arm without the original operator, so now we could, in theory, train our own operator (write our own device driver) who does understand welding (later graphics languages) as well as painting. However, our robot arm (GPU) still doesn't have any welding attachments. We could try to strap a welding rig to the arm (emulate the unsupported new functionality in software), but we'd have to pull additional workers off the line (use CPU time) to make that work. In fact, it would almost certainly take more workers to make this happen than the size of our current welding team (we'd end up with worse overall performance | Someone sat down and figured out how to work the robot arm without the original operator, so now we could, in theory, train our own operator (write our own device driver) who does understand welding (later graphics languages) as well as painting.

An updated version of | An updated version of android would be like restructuring the employees at the factory. Some older employees are retired, some underperforming employees are let go, and some new people are hired. But that won't change the fact that our robot arm (GPU) just wasn't built to do welding (support newer graphics APIs). |
