Food arrives in 30 minutes. Streaming platforms drop entire seasons at once. Packages show up the next day. Instant access isn’t a perk any more – it’s the baseline. But when everything is immediate, what gets left behind?
On-demand culture isn’t just about convenience. It’s subtly rewiring how we relate to time, patience and attention. As live tracking, rapid delivery windows and constant notifications become the background rhythm of daily life, a quieter question emerges: what happens when the world starts moving faster than we’re able to live inside it?
The shift isn’t accidental. Over the past decade, platforms have moved from competing on price to competing on speed – shrinking delivery windows from days to hours to minutes, and turning time itself into a product.
Neuroscience has long shown that our sense of time isn’t measured like a clock – it’s constructed, and far more flexible than we assume.
A 2022 study in PLOS Computational Biology, led by cognitive neuroscientist Warrick Roseboom, suggests we don’t rely on a fixed internal stopwatch. Instead, time stretches or compresses depending on what we experience. The more changes or “events” our brain registers in a moment, the longer it tends to feel.
Dr Devin Terhune, a cognitive neuroscientist at King’s College London who studies time perception, points to this idea: our sense of duration is shaped by how dynamic our surroundings are. “If your visual input keeps changing in a dynamic way, that might lead you to perceive a period of time as longer than it objectively is,” he says.
In a world of on-demand streaming, same-day delivery and instant gratification, our brains are rarely asked to wait – subtly recalibrating what “normal” time feels like.
For platforms, that recalibration isn’t a side effect; it is a valuable aspect of their success. Faster delivery and instant responses drive engagement and repeat use, making speed one of the most competitive features to optimise.
What’s being optimised isn’t just delivery speed, but expectation itself. As platforms compress the time between action and reward, they also reshape what users perceive as acceptable delay. The shorter that window becomes, the more friction any pause introduces – and the more valuable immediacy feels. In that sense, impatience isn’t simply a byproduct of on-demand systems, but something they increasingly rely on.
Our pull towards immediacy isn’t accidental – it’s predictable. Psychologist George Ainslie described it as “temporal discounting”: the tendency to prefer smaller rewards now over larger ones later. Research links this bias to brain regions involved in reward valuation and dopamine signalling.
When rewards arrive quickly and repeatedly – through instant deliveries, notifications or streaming updates – that bias is constantly reinforced. Over time, our perception of duration begins to shift: time feels compressed within these systems, and stretched outside them.
Terhune explains: “Brain regions that support reward processing do seem to play a role in time perception. If we grow accustomed to instant rewards, this is likely to increase our expectations for quick rewards and thereby reduce tolerance for waiting.”
That shift goes beyond behaviour. Gradually, it begins to reshape expectation itself. When immediacy becomes the norm, even small delays don’t just feel longer – they feel wrong, as if something in the system has failed.
Temporal discounting explains how we choose immediate rewards, but not why those choices can start to feel automatic. That’s where conditioning comes in.
Research on Pavlovian reward systems shows that cues signalling immediate rewards can push us towards action, even when waiting would be more rational. A preregistered 2025 study in Cognitive, Affective, & Behavioral Neuroscience found that participants exposed to cues for immediate rewards were more likely to act than those shown delayed ones.
In on-demand apps, those cues are everywhere. A promise of “15 minutes” or a driver being two minutes away doesn’t just inform – it triggers. Repeated exposure conditions us to expect speed, eventually lowering our tolerance for delay.
Waiting no longer feels neutral – it feels like friction. A delay of even a few minutes can prompt repeated app checks or irritation, not because it’s long, but because it breaks expectations.
These patterns aren’t just theoretical – they play out in daily life across the Middle East. Apps like Talabat, Careem, Noon and Amazon.ae have made rapid delivery a baseline expectation rather than a premium feature.
Across the region, mobile ordering now accounts for roughly 70% of food-delivery transactions – a sign of how deeply on-demand systems are embedded in everyday life. The market is scaling just as quickly, growing from $13.46 billion in 2023 to a projected $52.4 billion by 2030.
In cities like Dubai, where delivery in 15 to 20 minutes is becoming standard, waiting is no longer the default; it’s the exception.
As expectations compress, systems that cannot operate on-demand – from healthcare to public services – could risk feeling increasingly broken, even when they function as intended.
“When durations are longer than expected, or when we haven’t received an anticipated reward, we tend to attend to time more closely. Paying attention to time itself can stretch subjective duration,” Terhune explains. In other words, delays don’t just interrupt the experience but reshape it, making time feel longer than it is.
These patterns extend beyond personal impatience into broader social rhythms. Constant exposure to immediate rewards can shorten attention spans, increase stress and make even minor delays feel disproportionate. Waiting is no longer neutral. It becomes something to notice, track and react to.
On-demand services make life easier, but they also reset what waiting is supposed to feel like. As immediacy becomes the baseline, anything slower begins to feel like a disruption rather than a normal part of experience.
“Spending time in less dynamic environments, or in situations without rapid rewards, can help reset expectations,” Terhune says. The question, then, isn’t whether these systems are efficient – they are. It’s what happens as they quietly reshape our relationship with time itself.
Because if time only feels long when nothing is happening, the real shift may not be how fast the world moves – but how quickly we begin to experience anything slower as failure.
