What is Low-Code? – by Sophie Becker – Technically (substack.com)
Read the linked article.
Way back in my college days, we learned to program in everything from assembly language up through “high level” programming languages. Some of us even learned to enter boot strap code using front panel switches to enter machine code as bit patterns on a console!
Today, programming is simplified – tools like App Inventor illustrate this by using “drag and drop” programming methods, assembling programs from components, rather than typing in programing instructions.
Low Code does not necessarily divorce oneself from understanding programming concepts – but it enables the rapid construction of many functions – from user interfaces to underlying algorithms.
AI-based systems introduce a new level of automated code assembly. Go to Chat GPT, for example, and ask it to implement a sorting algorithm in Python – and sure enough, it will generates the source code in Python.
Two or three decades ago, the typical output of a software developer was likely to be a few hundred lines of code per day (at best, after integration, testing, and future modifications before final ship). New tools likely increase this by an order of magnitude or more!a
App Inventor is a “low code”, visual software development tool. Such “drag and drop” programming tools enable non-programmers (and programmers) to create many types of applications without the details of traditional programming code.
This leads to an important issue – will less trained/less experienced programmers inadvertently introduce security problems in their applications?
Gartner predicts that by the end of 2025, over 65% of development projects will use low-code builders. The field of low-code continues to expand. But what security implications does low-code introduce? Low-code refers to tools that enable application construction using visual programming models. Adopting drag-and-drop components instead of traditional code, no-code and low-code platforms enables non-technical folks to construct their own workflows without as much help from IT. Yet, handing power to citizen developers with less security training can be risky. Plus, low-code platforms may hold compromised propriety libraries or leverage APIs that may unknowingly expose sensitive data to the outside world. There’s also the possibility that low-code could increase shadow IT if not governed well.
How to Mitigate Low-Code Security Risks
That is the actual future of software development: It will become so easy and second nature, that for ordinary tasks you won’t even have to think about it.

Tools like MIT App Inventor, and others, are making programming so easy that it no longer requires extensive training and high levels skills to create many types of useful programs.
Writing code will become less and less necessary, making software development more accessible to everyone. This will allow people to solve new and unique problems for themselves, and true software engineers will continue to find ways to empower others through various platforms.
We used to call people who wrote programs, programmers. Later, this was change to titles like software developer, software engineer or sometimes computer engineer. Today, the media has short circuited the entire field to just “coders”, which seems like a downgrading of skills and title.
Some new “extension” features are available for testing in App Inventor at MIT App Inventor Extensions. The 4 extensions include vector addition, simple image processing, simple audio processing to identify the pitch of a sound, and the addition of multi-touch gestures to the Canvas.
I have not yet had time to try these but this is a sign of things to come as 3rd parties can begin to develop extensions to the core set of App Inventor features.
Look forward to trying these out! Click on the link above to take a look.
