DDR5 isn't normally associated with AI accelerators. Those typically employ GDDR or HBM, which trade capacity for the higher bandwidth required for those workloads. However, the systems into which these accelerators are deployed do use DRR5 for the system memory to feed the CPU and to store intermediary data, like the key value caches used to prolong a model's short-term memory over extended periods.
The twin robotic spacecraft launched in 1977, the same year as the Apple II, the TRS-80 and the Commodore Pet, making the spacecraft the patron saints of the modern computer age. By the time Voyager's primary mission ended with Voyager 2's 1989 Neptune encounter, earthlings had the 80486, the Gameboy and the Apple Macintosh Portable. As Voyager 2 was nearly three billion miles (4.7 billion kilometers) away at that point, however, hardware upgrades were ruled out by the cost of delivery.
