Does "is potentially faster" imply "is not slower"?
Someone said to me, "X is potentially faster than Y". Without any clarification at that point, I immediately assumed that the speaker thought that X was at least not slower than Y.
It was revealed in a further discussion, however, that the speaker did not know much about the current performance of either X or Y. What they meant was that, if both were given equal opportunities for optimisation, X would certainly end up faster (and, probably, that it might already be the case).
I agree that "potentially so and so" can certainly translate that way, i.e. something merely has the potential to be so and so. My question, however, is about an implication of "potentially" when it is used in a comparison.
So, when I hear, "X is potentially faster than Y", is it normal, without more information on the subject, for me to assume that X is at least not slower or should I wait for more information before jumping to a conclusion? Does it depend on the situation (e.g. heard in a conversation vs read in a technical article)?
No. The implication I get from "X is potentially faster than Y" is either:
- In some circumstances we know about (for example, in the circumstance that the code is optimized for both X and Y), X is faster. In other circumstances we know about, it is the same speed, or slower.
- We don't know in which circumstances X is faster; for any particular case, it could be faster, or it could be the same speed or slower.
In neither case is there an implication that X is never slower than Y.
No. A potential state can be quite remote and independent from a current state.
No. "is potentially faster" makes a restricting statement on the speed, namely that it "is [not [definitely [not faster]]]". In other words, it is possible that it is faster.
No further restrictions to the speed are made. Thus, it might or might not have the same or a lower speed.
