I upvoted this, but it is not accurate. If you're French then you may be misled by the combination of two signals: "Ecole Polytechnique (X)" (aka "social status") and birth date (aka "old"). This gives "boomer" hence the sarcasm.

Now that memories are mentioned, I'm not a grand-pere, nor French. Grand-peres are proud of their '69 youth. Yes, they stopped the social elevator and I share your opinion about them. "X" was relevant only for the availability of (mostly empty) rooms full of "unix workstations" and the friends I made in Paris. During this time, your grand-pere probably was vaguely proud about the minitel and a bit disturbed about the fact that people like me are allowed to study at X.
