Post-tech

Post-tech is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Post-tech rather than just read about it. In short: Post-tech, (or post-technology, post-digital-technology) is a type of technology that is more concerned about being human than about technology. It advocates a design that is not merely focused on efficiency and exploiting users by increasing their time spent with digital devices and technology itself but to support the user's focus and intent, well-being, and independence (from technology).

Key takeaways

Post-tech belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Post-tech to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Post-tech from memory before moving on to harder problems.

Reference excerpt

Post-tech, (or post-technology, post-digital-technology) is a type of technology that is more concerned about being human than about technology. It advocates a design that is not merely focused on efficiency and exploiting users by increasing their time spent with digital devices and technology itself but to support the user's focus and intent, well-being, and independence (from technology). With this interstitial spaces could also be created, similar to what Michel Foucault describes as heterotopia.

Worked examples

Example 1 — a first encounter with Post-tech

Start with the simplest possible case. Write down what Post-tech claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Post-tech before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Post-tech ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Post-tech

In research: Post-tech appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Post-tech in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Post-tech is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computing stubs, Human–computer interaction, Postmodernism, so understanding it makes those chapters shorter.
In everyday life: Look for Post-tech outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Post-tech in simple terms?

Why does Post-tech matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Post-tech?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
