Fast iterations to begin to see the logic play out and then loop back to alter your logic.
1. do a thing
2. check it against criteria
3. alter to fix things that aren't quite right
4. go back to 1
Also known as the OODA loop[^]:
It works!

tldr; your message, and from skimming the content for sure the book.
skimming it "just coz it compiles it's not good code" yeah, but that takes him how many words?
Oh wait, that was not only the the first excerpt, two more excerpts that say... exactly the same thing using different words. Way to turn one single sentence into a whole book!
lets substitute "programs, programming" etc for cars, mechanic-ing (and of course the tools named etc), "The Secret Life of Vehicles: Understand Cars - Craft Better Transporters" - just as appropriate, let's fill the book up with how people have done it wrong -
... "just because it looks and moves like a car doesn't mean it's wise to use it on the road."
Now let's change it from cars to
- trading shares. Just Because you made a few pennies doesn't mean you should quit your job yet.
- Heart surgery: Just Because the patient woke doesn't mean it's going to last.
- Raising Children: Just Because they didn't starve doesn't mean they're good.
....
self righteous - make yourself look smart by pointing at other peoples failures.
thanks for the heads up, I know for sure it's not for my reading list.
(yeah I know some people like reading theory stuff,
some of us though have better things to do chores the missus told us to do.)

I may pick up that book, and I might find a lot that I agree with. I am of that generation.
In a chat yesterday with a co-worker, I repeated one of my mantras that certainly is related to this thread: You should always strive to fully understand what is going on at least one layer below the one you interface to. He nodded: A far too high fraction of younger, newly educated guys are satisfied something that works, automagically, without the faintest clue of how it is done, not even immediately below the API surface.
But then...
In my days as a student, we learned about e.g. disk scheduling algorithms - FCFS, SSTF, elevator... - but in my first summer job as an intern, forty years ago, I learned that a computer system who had more than one pending disk transfer more than 5% of the time was severy overloaded. All this fancy disk queue sorting algorithms was 95+% of the time "sorting" an empty or 1-element list. We also learned about how to compose a good job mix - putting I/O intensive jobs together with CPU intensive ones to obtain as close to 100% utilization of each class of resources (in the Job Control Language you could give indicators of expected load on various resources). Time sharing, interactive terminals and such was a new thing, not yet mainstream.
Some knowledge gets outdated. Noone need to know disk scheduling, sectors, tracks and platters on a flash disk. Job scheduling is specialist knowledge for those who manage supercomputers. Knowing how to knit together a block of core can be fun at the computer museum, but it should not be treated as essential knowledge.
Some of what we learn in school is of the kind "know what is going on at least one layer down". We learn how 4-stroke and 2-stroke combustion engine work. More than half of the new cars sold in Norway this year will be electric ones. In my days, we learned the chemistry of silver photography. Today, the ordering time for darkroom materials (chemicals, paper) is weeks or months, you no longer have any use for that knowledge.
But you did. Not because you became a car mechanic or photo lab worker (you didn't), but to know how things work. Kids learned to play a keyboard with MIDI interface to become great musicians, but to get a ceratain feeling for how it is to perform music. They did learn to create music, at a certain level. I think that is valuable knowledge, even when it is only useful in family parties.
What attracted me to programming was way you (must) approach a problem: You just have to do it in a systematic and orderly way ... at a certain level. You must do things in the proper order. You must split the task into subtasks that can be solved one by one. I do not think of my first computer experiences as "programming", but as "orderly problem solving". Actually, for a few years I was evangelising programming for everybody not as a way to control a computer, but as a way to learn general problem solving methodologies, applicable in almost any problem area.
When I was teaching elementary programming (at college level), the "problem kids" were the self-taugt C gurus who "knew how to program". The easiest ones were those who had been playing with similar tools/toys, like visual languages. Today, programming an Arduino to make some LEDs flash would be fine - so different from large-scale programming that they don't think they are gurus. Yet, they have learned how to approach a problem in a somewhat systematic way.
I wouldn't turn down Blockly any more than I would turn down the piano playing of my neighbour's nine year old. They both represent the idea of knowing how things work, even if you are not the one who will be doing the real work.

Very good points and a very interesting post.
Of course the short excerpts don't quite communicate everything the author is talking about.
I think the point is that :
In every realm where you learn there is often much more going on below the surface than you might think. Learn those foundational things and how to think about those things and you'll be stronger at whatever you do.
And for sure the "shortcut" types of things that help someone get introduced to a subject can be very good -- and the real problem may simply be that no one was there who told the person that "learning these things this way is just to stimulate interest, but don't believe you are going to play the Recorder[^] professionally, because there's not a lot of professional Recorder Concerts going on out there."
Of course, someone will post a youtube of the most famous Recorder Player who can play everything from Bach to Bon Jovi and that'll prove that Recorder concerts are going on everywhere. 
I think the computer is a place where a lot of sub-activities are going on and you can be totally unaware and then learning those things can really help you understand things better. But, of course, this takes time and you can't just learn all of the subactivities and if you wait until you understand all of that the student will probably run away.
Good talk.

The time, effort, and money would be better spent if they taught them science - in particular chemistry. Not deep dark chemistry but the chemistry involved in daily life and some enrichment beyond that - so they're not taken for suckers by scammers and politicians who make stuff up.
Why chemistry? Well, physics would also be good - but the current attitude vilifies chemistry and 'chemicals' - product making the preposterous claim they're 'chemical free'. Really - take a look around you and realize how little would be there without chemistry.

Yes, teaching them:
1. Critical thinking skills-- when you see something, ask what might be behind that something
2. Foundational things -- Matter is built out of atoms. Atoms have properties. Types of atoms behave particular ways. Some atoms form a gas that could kill you if you breathe it Cl or explode if you put it in water Na. If you mix certain atoms you get a compound and this compound may be safer (NaCl) or may burn a hole through you (HCl).
I like that the author is attempting to draw readers into the foundational things.

used to be physics held things together and chemistry made it pretty
then chemistry invented explosions (often still pretty though).
[not to be outdone] physics made even bigger explosions (big enough that observers didn't notice what color it was).
biology: messing with diversity, genetic alteration, cloning...
computers: fraud, identity theft, fake news...
economics: rob the poor, overfeed the rich, money laundering...
...
science is dangerous and evil! ban it all!

Odd that you'd pick that - as I recall, the bible-pounders have been trying to ban (or more recently, corrupt) science.
Political Correctness (usually considered left-wing) can induce nausea - religious fervor (usually considered right-wing) is outright dangerous.
New rule for everyone: when you want to point out the flaws in "Them", do so while pointing into a mirror.

Yes, but you are commenting on something which is a subset of a major problem. The same issue applies to politics, business, in fact most human endeavours. We lose sight of the essence of what we do.

I am the same, this kind of stupidity really annoys me.
However, I also understand that these kind of statements are caused because the general public reader is even more stupid. What is common sense to some of us is unfortunately not common sense to the majority.
People will lick toilets then complain when they get ill saying "well, nobody said NOT to lick them". Then next week there will be a sign "DO NOT LICK TOILETS. MAY CAUSE SICKNESS". 
Living on this planet is a daily struggle.

We have a regular event at our local Club for which we use a supplier to bring in food and I get the joy of doing the admin.
This week I had a phone call as a gentleman was desperate to change his order of chicken to fish as he considered chicken too high a coronavirus risk.

I guess the sensible thing to do in that situation is just bite your tongue, agree to process the request, and try and forget the conversation even happened as soon as possible

tell him fish has a higher risk of Ross River,
if he chooses beef, JKD (or whatever it's called now)

I mean just for the fun of it put him off off all the choices except tofu.
later on when eating remark loudly how "juicy" your [choice of] meat is.

Very true. The posters made in India about the virus feel very obvious but still, it's much needed. Just thinking about the folks in rural areas. They are the majority.
And most importantly think about our Prime Minister and all the politicians. They would be the number #1 consumer for these posters.
