Ephemeral..? You should have said much-vaunted, or specious, or dubious.
Ephemeral means lasting a short time, tending to go away quickly.
You used the word without knowing what it means.
You're too old not to automatically dislike new tech but too young to know the meaning of the words you use.
No fool like an old fool, right?
I meant fleeting, short-lived, as in:
Ephemerality is the concept of things being transitory, existing only briefly. Typically the term ephemeral is used to describe objects found in nature, although it can describe a wide range of things, including human artifacts intentionally made to last for only a temporary period, in order to increase their perceived aesthetic value.
Perceived aesthetic value, like a high-end, virtue-signaling, short-lived electric car.
No fool like an old fool. Indeed.
