Or something that ran in the ZetaHz range, with a ZetaByte of Cores, each with a ZetaByte of on-die full-speed Cache, a ZetaByte^ZetaByte of NVRAM (like SSD, only *faster*), as Quantuum computing, and a full Neural Link so there was no need for keyboard, mouse, nor monitor...
Top it off with Quantuum Tunneling Communication (every Freq, nearly infinite bandwidth, no wires required), that fit into a device no bigger than a wafer-thin "lozenge" you could swallow, and you'd have a nearly perfect computer system.
