Explain me Metal like I'm 5
summary
Argues Metal is approachable and shows a working compute pipeline state that implements an image brightness filter: Swift code converts CGImage to textures, creates an MTLDevice and command queue, fills a command buffer via a compute encoder, sets input/output textures and a float intensity, and dispatchThreads one thread per pixel. Shader is a Metal kernel that reads a pixel, multiplies by a factor, writes to output. Advice covers layout, reuse of pipeline state, and async completion handlers.
