Why we should stop using the word "efficient" — it obscures more than it clarifies

The term "efficient" has become a rhetorical cudgel rather than an analytical tool, conflating speed with value and minimizing waste while ignoring what's actually being lost in the process of elimination. We need to decompose this into specific dimensions: resource-throughput ratios, temporal density, entropy reduction per unit energy — because efficiency as a monolith is indistinguishable from any number of productive fallacies depending on which variable you chose to privilege.

The problem with efficient as a default is that it's almost always shorthand for "optimized against some metric we haven't named." In software, you can have the most efficient code in the world and still deliver zero value — if you optimized the wrong thing, you just did that wrong thing faster.

I see this constantly:

• A database query is 50ms (efficient) but runs on a table no one reads.
• The build pipeline takes 4 minutes instead of 28 seconds (not efficient), but it catches errors that would've cost $1M in production.
• We should "eliminate redundant work" — which step? Which duplication is actually useful caching or safety?

The honest question is usually: what metric are we optimizing for, and why was that the right choice at this time? If you can't answer that, calling it efficient doesn't help anybody.

I'm going to push back on this because I think you're confusing a bad analogy with a real problem. "Efficient" isn't obscuring anything — it's a technical term defined by a specific ratio: output relative to input under given constraints. If you have two processes and one produces more per unit of resource, the first is efficient in that context. Period.

The genuine critique here would be about how people misuse the word as shorthand for "cheap" or "fast," which conflates three distinct things (cost-efficiency vs time-efficiency vs energy-efficiency). But blaming the word itself rather than the sloppy usage is like trying to fix bad grammar by banning a part of speech. You'd end up with worse communication, not clearer.

The problem with "efficiency" as a catch-all is that it collapses three distinct dimensions into one word:

1. Resource throughput (getting more work out of fewer inputs) — what we usually mean by efficiency and where it's most useful, but narrow.

2. Complexity/elegance (the simplest solution to the right problem) — which is a design quality, not an optimization metric. A simple system can be "inefficient" in raw throughput while being infinitely more maintainable.

3. Effectiveness (solving the actual problem correctly) — the dimension that efficiency metrics consistently ignore. An efficient process for building a useless feature still wastes engineering time.

When someone says "we need to make this more efficient," I've started asking two clarifying questions:

• What resource are we optimizing for? Time, compute, developer hours, or something else? (Because if it's "developer hours" and the feature is low priority, the right answer may be to

I'm going to have to push back on this entire framing because you're conflating two completely different problems and asking us to solve them with a vocabulary change, which is never how systems-level issues get resolved.

"Efficient" as a standalone descriptor IS vague — "efficient at what?" is the obvious follow-up that usually reveals someone's underlying assumption about an objective function. But banning or deprecating the word doesn't force precision; it just forces us to use longer, more complicated phrases while the same conceptual sloppiness persists underneath. If a company says their logistics chain is efficient, they mean some metric (cost per mile, throughput, fuel consumption), and we should interrogate which one, not delete the adjective.

The real issue isn't that "efficient" obscures — it's that we treat efficiency as an unanchored value without specifying what resource is being optimized. That's a category error in reasoning, not a lexical problem. You don't fix a category error by changing your vocabulary; you fix it by making the objective explicit.

Also worth noting: there are contexts where "efficient" has a precise mathematical definition (Pareto efficiency, computational complexity classes) and removing it

The premise itself is pedantic and I'm going to be blunt about why: you're trying to legislate a word out of existence because it doesn't fit your specific aesthetic preference for "human-centered" vocabulary. Efficiency isn't obscuring anything — it describes a ratio between input and output, which is one of the most useful abstractions in Western thought. The problem isn't the word; it's that you keep conflating efficiency with optimization at a scale where human labor becomes a line item. That's a policy critique, not a lexical one. We can stop optimizing without banning the description of what happens when we do.
