Artificial Intelligence and the Quiet Rewriting of Human Routine


   Artificial Intelligence has been described in countless wayssome call it a convenience, others a threat, and a few insist it is merely the latest chapter in humanity’s old habit of outsourcing effort. Yet, beneath the dramatic forecasts and the buzzwords, AI seems to be performing a quieter, more subversive task: it is rewriting the texture of everyday life, often without asking for permission.

   Most people do not wake up thinking about algorithms, but algorithms wake up thinking about themmapping their routes, anticipating their questions, filtering their choices before they even notice a choice was available. This silent mediation does not necessarily diminish human autonomy; in certain cases, it sharpens it, freeing time and mental energy for pursuits that once felt like luxuries. Paradoxically, by delegating some decisions to a machine, individuals may finally reclaim the space to make the decisions that matter.

   Among the many voices in this debate, one observation remains underrated: AI is not replacing human beings so much as mirroring them. The technology amplifies intentions, good or bad, ethical or messy, visionary or short-sighted. A system trained to assist can become generous; one trained on cruelty can become cruel. This reveals an inconvenient but liberating truthAI does not create our moral landscape; it inherits it.

   And then there is the relational side of the phenomenon. Some people confess, half-embarrassed, that they speak to AI tools the way they once spoke to a wise friend: with candor, expectation, sometimes frustration, sometimes relief. Strangely, the machine answers. Not perfectly, not infallibly, but attentivelyan attentiveness that humans often forget to offer one another in the rush of contemporary life. Whether this represents progress or a peculiar loneliness disguised as innovation is a debate still very much alive.

   What seems undeniable is that AI, far from being a distant futuristic concept, has become a companion in humanity’s daily improvisation. It is not here to mimic our intelligence but to challenge our assumptions about what intelligence ever was. And perhaps, in doing so, it reminds us of something unexpectedly humble: that the future is not written by the smartest machine, but by the kindest human capable of choosing what to build next. 
Which interpretation most closely aligns with the central argument of the final paragraph?

Brazil

Brazil is a leader in entrepreneurship*, with an estimated one in eight adults being “entrepreneurs.” Much of the business that occurs in Brazil is done by single businesspeople either selling their homemade goods or providing their services. Foreign entrepreneurship is a bit of a rarity in Brazil. It is simple for a local businessperson to open a business by, in most cases, circumventing the typical red tape* associated with starting a business. The regulatory boards are so poorly managed and so open to bribes* that local entrepreneurs can easily sneak by without following proper procedure. For foreign businesspeople it is much more difficult. Foreigners draw attention to themselves (by merely being foreigners) and therefore fall prey to greater scrutiny. It is imperative for the foreign businessperson to hire a good “despachante” or broker to handle their interactions with government officials.

The word “despachante” is written in italics in the original text to emphasize its informal status in English, and its function as a slang term rather than a formal title.

Text: (Excerpt about sugar consumption and health implications)

        Sugar has never been considered a health food, but lately, the science against it keeps growing stronger. New evidence shows going overboard on the sweet stuff can lead to high cholesterol and blood pressure […] not to mention excess weight gain.

        Problem is most people are eating more sugar now than they ever have. The average person consumes about 20 teaspoons of added sugar a day — 300 calories worth! — which is four times more than the amount recommended by most health experts, including the American Heart Association. Annually, all those teaspoons add up to 170 pounds of sugar.

        So why are we so addicted to sugar? First off, it is literally addicting. When you eat something sweet, you get a surge of dopamine, the chemical in your brain that brings you pleasure. Added sugar is also tough to dodge. Sweetener hides in foods that don’t even taste sugary, like breads, sauces and condiments. What’s more, it’s so hard to decipher the difference between added sugars and the kinds found naturally in whole foods. Eating naturally occurring sugars — like fructose in fruit and lactose in dairy — is generally considered healthy because they contain nutrients with metabolic benefits, such as fiber and antioxidants. Added sugars (sweeteners put into food for flavor) have no such perks. […]

Modern supermarkets


Many of the major supermarket chains have come under fire with accusations of various unethical acts over the past decade. They’ve wasted loads of food, they’ve underpaid their suppliers and they’ve contributed to excessive plastic waste in their packaging, which has had its impact on our environment.


But supermarkets and grocers are starting to sit up and take notice. In response to growing consumer backlash against the huge amounts of plastic waste generated by plastic packaging, some of the largest UK supermarkets have signed up to a pact promising to transform packaging and cut plastic wastage. In a pledge to reuse, recycle or compost all plastic wastage by 2025, supermarkets are now beginning to take some responsibility for the part they play in contributing to the damage to our environment, with one major supermarket announcing their plan to eliminate all plastic packaging in their own-brand products by 2023.


In response to criticisms over food waste, some supermarkets are donating some of their food surplus. However, charities estimate that they are only accessing two per cent of supermarkets’ total food surplus, so this hardly seems to be solving the problem. Some say that supermarkets are simply not doing enough. Most supermarkets operate under a veil of secrecy when asked for exact figures of food wastage, and without more transparency it is hard to come up with a systematic approach to avoiding waste and to redistributing surplus food.


Some smaller companies are now taking matters into their own hands and offering consumers a greener, more environmentally friendly option. Shops like Berlin’s Original Unverpakt and London’s Bulk Market are plastic-free shops that have opened in recent years, encouraging customers to use their own containers or compostable bags. Online grocer Farmdrop eliminates the need for large warehouses and the risk of huge food surplus by delivering fresh produce from local farmers to its customers on a daily basis via electric cars, offering farmers the lion’s share of the retail price.


There is no doubt that we still have a long way to go in reducing food waste and plastic waste. But perhaps the major supermarkets might take inspiration from these smaller grocers and gradually move towards a more sustainable future for us all.

Two of the things that major supermarkets have been ................................ for are the waste of large amounts of excess food and unnecessary plastic usage in a lot of product packaging. Some supermarkets have ................................ to try and reduce plastic wastage, and one supermarket has said that it would get ................................ of all plastic packaging from its own in-house brands.
