The absurdity of an idea is often a context-dependent judgment, primarily grounded in the present knowledge and capabilities. The fact that something might become possible in the future does not invalidate its classification as absurd in the present moment it was judged. The "flaw" isn't in the initial judgment of present absurdity, but in the potential overconfidence of applying that present judgment universally to all future possibilities, or in failing to update that judgment as knowledge advances.
When used in fact based context dependent statements, assertions of absurdity are objectivly true in that moment but do not negate the potential for new information to dismantle the assertion.
Crucially, asserting that a notion is an absurdity heuristic does not validate speculative credulity.
I feel the same of both but I will say Gemini feels like it is better at not gassing me up when I ask for feedback. On the other hand, It is the only model I've had that fundementaly did not understand a question I asked. It has done that twice now, once on the previous version and the other on the most recent.
