It's a good story but it kind of ignores something fundamental. Most early writing systems were created for accounting, like Bob gets 5 wheat, Doug gets 5 sheep, etc. In a world where computers are some ancient artifact, they would still have significant value as calculators and accounting tools. It's likely some scribe class would emerge around using them to manage the day-to-day of whatever social hierarchy is present. Visicalc will never die!
