Guinness claims that the IBM System/360 (1964) was the first computer to use integrated circuits. I've tried unsuccessfully to convince them that they are wrong. The Texas Instruments Semiconductor Network Computer (1961) was the first, a prototype system, followed by multiple aerospace computers earlier than the System/360. Moreover, the System/360 used hybrid SLT modules which weren't even integrated circuits, so it's not even a contender. Maybe you could argue that the System/360 was the first commercial, production computer to use high-density modular electronics, but that's a lot of extra adjectives.

Guinness started out as a joke. And if you look at the diversity of records it has, it definitely falls in the theme of a joke

Not to mention, being used as a whitewashing tool by autocrats across the Middle East and Central Asia (for no reason other than a dick measuring contest).
