For me, using my mouse while I'm working feels natural, so trying to change my workflow to learn how to navigate everything by keyboard would be a huge amount of extra effort just to maybe possibly save a little bit of time in some situations.
Again, there is no universal correct answer. Sometimes the keyboard really is better. However sometimes the mouse really is better and because I'm proficient in it I don't break my flow to use it.
I been doing a lot of Bender. Keyboard on left hand and Mouse on right. The keyboard shortcuts in Blender are excellent, but there are _many_.
I know this sounds silly, but what really breaks my flow is moving my mouse from the middle of the screen where my model is, to the top of the screen where the menus is.
I bought a Stream Deck which is a programmable keyboard with 32 buttons and a screen behind them. I've programmed my most common commands there, so I can just reach across with a finger and smash a button rather than move the mouse away from the center of the screen.
It saves about 1 second, but really makes a huge difference.
By this logic a person who were comfortable with mouse should never grow to like VIM.

Fundamentally a computer is something that execute instructions. It is pretty poor interface to pick instructions from 100 options using a mouse as opposed to type it using a keyboard. A mouse hides the power of the computer behind a set of fixed clickable options. That is a pretty poor interface.
Quite the opposite, my argument is that habits are changeable.

You continue to argue for my point. OP was claiming that measured efficiency does not matter because it's about "flow". I argue that one can teach oneself to flow differently, the commands can be learned.
There is more than selecting options. Selecting text is normally better with a mouse.
We are not talking about keyboard shortcuts (key combinations that you press to do something) by the way, and about the actual typing of commands in the terminal/shell/repl what ever...
Your argument is sound but this overstates your case a bit. There's a reason we don't type with our toes.
All of this brings me to my questions: Why do you reject measuring how good an interface is? Or given your dismay over keyboard based workflows, why do you think they would win most of the time?
I'd wager that if actually tested, in only a few scenarios the keyboard would win, while hybrids (with both mouse and keyboard input) perform best for most people.
https://danluu.com/keyboard-v-mouse/ - """The widely cited studies on mouse vs. keyboard efficiency are completely bogus ... <testing, reading, etc.> When I look at various tasks myself, the results are mixed, and they’re mixed in the way that most programmers I polled predicted. This result is so boring that it would barely be worth mentioning if not for the large groups of people who believe that either the keyboard is always faster than the mouse or vice versa."""
How someone interacts with your software is absolutely measurable and the results will vary by how a user is likely to use it in frequency and variety of function. Someone that needs to do something specific with your software every day will interact with it quite differently than someone that just hops onto it every now and then to do a different task each time.
All of this requires actual studies and observation of users over time. Micro benchmarks have no space there. Testing how fast a find and replace is is meaningless. In case of software for writing text you'd test a user actually writing prose, changing font sizes, title colors, and maybe replace a word over the file too. You would have commonly used functions mixed in with less commonly used functions over how the software is used under a specific use case. (For example, writing text, revising text, and polishing a graph representation are different use cases)
This is not easy, which probably why it's not done all too often, but it is also most definitely unlike a micro benchmark (which your link argues against).
All that being said, I don't know of any person strictly pitting mouse against keyboard when testing UI for possible improvements.
For tools that are mainly for non-text visual information, then the keyboard versus mouse debate is much more heavily weighted in favor of the mouse. Even then, there are times when effective keyboard shortcuts are far more useful than menus and icons. Take any CAD or 3d modeling software as an example. 90% of what a user does will be interacting with visually-presented spatial data, but even then knowing the shortcuts for changing tools or modifying a tool's settings will make you much faster and remove the need to constantly navigate nested menus of options.
What I take issue is with tools that make them hard to use with low contrast between widgets or shortcuts that does not work if a text input is focused. Also tools that forget they have a primary usage and wants me to know everything at once (notifications, big action buttons, guided tours and what not).
That's because it's practically impossible to collect objective data here, i.e. without confounding factors.
A product where the user spends 99+% of their time reading/consuming is almost certainly easier to use with a GUI. The market settled on thumb-flicking for doom scrolling instead of a button or scroll wheel interface, for a reason.
A product where the user spends 99+% of their time writing is almost certainly easier to use with a keyboard. Most sane people do not write essays on their phones with two thumbs; a keyboard and a proper word processor are preferred.
Most products fall somewhere in the middle. Most products have multiple interfaces, some primarily for consuming information and some primarily for producing it, and thus would find different inputs more productive in different modes. When people claim that they find one input type is more productive than the other, most likely is that their particular use-patterns fall more in-line with the one most aligned with their use-patterns.
In a large number of cases people who say they are more productive have never measured it. They have no idea if it is true. There are been many competitions between keyboard and mouse navigation over the years. Depending on the details of how the test is written one will win or the other, often by a significant amount, in many cases the loser is the one that user said was more productive before seeing the real results.
