Can software be built similarly?
-
You beat me to it. If there was a blueprint that was 100% thorough, already done and thought out, etc. then in theory that could happen. But, software dev is never like that. People want change and customization when they hire custom dev work... otherwise why hire devs. So, in reality that theory never holds up.

Totally agree. The comparison I was making before (design = writing programs, build = compiling/linking) is not mine. I read it somewhere but I find it very true and it also "explains" other differences between software projects and construction projects. Stuff like why software piracy is a lot more prevalent than bridge or house piracy. You can get plans for my house from city hall but building it is still gonna cost you a good chunk of money. Meanwhile if you get my source code, building it takes mere seconds. Also changes like adding 10 meters to a bridge, or an entire traffic lane: this is done, but the result is a new bridge and it will be built in 30-40 years when the current one was amortized. That's because building is so expensive. For software, building is incredibly cheap and people are asking for new versions all the time, ignoring the cost of design.

In short, no. What was built is not what you would call a full hospital. It's more a stripped-down "hospital" with well understood modules that could be mass-produced and assembled like Lego. The same with a railroad, where everything is a known, small, and easily assembled. The skyscraper was the same way. A simple skyscraper, with nearly every floor the same, easily mass-produced, brought to the site and stacked. Is it up to the standards that we would use? No. Seriously, have you seen some of the software that comes out of China? China doesn't build software like they build those buildings.

He wrote:

Espressif (a fabless semiconductor company out of China) makes decent software for their MCU products. The ESP-IDF for the most part is well thought out, and easier to code against than many other embedded software frameworks.

In a word, no. As someone else mentioned here, building software is equivalent to the design phase of building hardware. I guarantee that the design team for the railway took longer than 9 hours to plan the railway, and that adding people to the design team would not have materially shortened the design process.

As I recall the discussion to which you refer is re/ projects in full progress and significantly advanced. The articles to which I refer are projects which are fully designed though yet to be implemented. Assuming the design of a software project is complete well documented and accepted it is not obvious to me why 100,000 programmers can not be hired to implement one of each of the 100,000 methods of the project and bingo presto voila the project is complete in no time at all and ready for integration test.

Because software engineering is not a task like making toast or painting fences. (With no offense to makers of toast and painters of fences.) Methods aren't worked on in isolation. While a 100K engineers could write a 100K methods in a few minutes, they can't design a 100K methods in a few minutes. /ravi

I think "built" is the wrong use of words. I would use "assembled". If the plans are done, and you just need to implement according to an established standard by assembling pre-established components according to a pre-established pattern. . . then yes. Kind of the way that building a car can be done by hand, but usually it's done on a production "assembly" line. That's one of the tantalising possibilities of low code environments. But just because, you can, doesn't mean that anyone can, or that the results are spectacular. Methinks doing work very rapidly has implications with regard to quality, and what might be accepted and acceptable.

I have limited experience re/ large software projects. I was imagining an initial lengthy process of design specifying all or as many as possible of the classes functions etc. required in terms of their interfaces only leaving details of implementation to each of the 100,000 assigned programmers. So no pre-established components rather pre-specified components.

order of arguments
Like one of my pet peeves about .net:
public ArgumentException (string? message, string? paramName);public ArgumentNullException (string? paramName, string? message);public ArgumentOutOfRangeException (string? paramName, string? message);In my opinion,ArgumentExceptionhas the parameters in the correct order.It looked strange to me at first, but I think I get it. With the ArgumentException it's not clear what is wrong with the argument, so you must specify a message for further details. In that case the paramName is secundary because it could also be hard coded in the message or the error could relate to multiple parameters. With the Null and OutOfRange exceptions the error is clear even without a message and a default message would suffice, so you'd rarely specify a message. What's more important is what parameter the error refers to. Hence the "switch" in parameter order.

You confuse building with planning. In software building is actually compilation/bundling or running software step. Programming is planning like planning layout of tracks or planning rooms, which equipment should be where etc.. How long did it take to make plans for railroad or hospital? Keep in mind they most likely had already existing plans like having plans for emergency hospital ready in case they need them. But creating those plans most likely took much longer or those plans were reused from existing ones. Most likely all building components were prepared beforehand and no one counted time how much it takes to align stuff before you can "build a railroad in only 9 hours" - I can say by bringing in tools and materials for 3 months or more in advance.

Yes. It could be.
As pointed out previously, the design, structure, materials, etc. used for buildings are all standard. You don't have 40 different companies each with their own 'unique' way to build a building/room/wall/floor/etc. Each building may have slight modifications based on needs, but are generally minor modifications not greatly affecting the overall timeline of the build.
Yet in the software world, there are multiple 'unique' systems for financial institutions, purchasing, inventory, medical, insurance, etc. All the systems of same-type are primarily providing the same service but developed/programmed differently.
Software could be simplified to the extent of building a building if a single programming language could be developed and used to build a standard base system/application, and standard add-on modules, and a tool to modify the standard modules as needed, be it drag-drop, editing, etc. Then projects could be completed in much faster, reducing time and costs.
There would only be one financial system, one purchasing system, etc. Just modify it as needed, or pay for the features as needed.
But this would make all current languages obsolete. Many would loose jobs since the reduced need of programmers knowing defunct languages, except to keep current systems maintained. There would also be a reduction of duplicate developement projects, reduced need of project managers, architects. AI would also gain a stronger foot-hold in development based on the new standard language. If a bank could ask AI online to produce for them a system with x,y,z features, it would be like ordering a fast-food burger, hold the onions, add cheese and bacon.

The thousands-of-programmers model assumes that the most time-consuming part of software development is typing the code into an editor. Designing the software is really the biggest piece of work, and it is more difficult to serialize because of the need to agree on a contract between any two communicating parts. Building software as pipelines or loosely coupled modules can help with this, but there is only so much available concurrency in the design process.
