Palantir CEO Alex Karp has claimed that a US general once requested the company to build an “alien anti-gravity machine.”
Karp made the comments during his talk at AIPCon11 regarding engineers and government contracts.
And, as Palantir makes data integration and analytics to cooperate with military defense (as well as other fields), regular conversations with army personnel regularly happen between the tech giant and US forces.
However, Karp said the general understood the battlefield but “didn't know much about tech,” which created a clash between what was fantastic versus what was actually possible to build.
According to Karp, the unnamed general wanted Palantir to build him “this bullshit alien anti-gravity machine that also tells me I'm brilliant.”
Karp did not identify the general, the military branch, the program involved, or whether “alien anti-gravity machine” was the official description, in a rather theatrical speech, as has become his trademark style.
One of Palantir’s forward-deployed engineers reportedly pushed back directly, telling the general:
But you're not smart enough to know how dumb you are,Palantir CEO Alex Carp claimed one of his engineers told a US general.
Karp acknowledged that the engineer was not supposed to speak to a senior military figure that way, but argued that the confrontation was “really, really important” because Palantir’s engineers need to challenge customers when they are asking for the wrong thing.

As such comments would normally stir up a debate about the US government or even private companies dabbling in reverse-engineering from alien ships, Karp's flamboyancy drew up more attention on the Reddit r/UFO forum.
“This guy is out of his mind” said one Redditor, while another commented that it was reminiscent of stand-up comedy.
As private companies continue to come under the spotlight in the UFO disclosure debate, perhaps a more grounded discussion with such senior figures would allow it to be taken more seriously in such instances.
