WiFi's trajectory suggests remarkable staying power despite rapid technological evolution. From 802.11b's 11 Mbps in 1999 to WiFi 7's promised 46 Gbps, the protocol has maintained backwards compatibility whilst increasing performance by four orders of magnitude. Industry projections place WiFi as a dominant connectivity method through 2040, even as 5G and satellite internet expand. The technology benefits from installed infrastructure worth trillions and standardisation that ensures interoperability. However, WiFi faces existential questions: will direct neural interfaces eventually render radio-wave connectivity obsolete? The 25-year-old technology shows no immediate signs of decline, yet operates in a domain where disruption is constant.

WiFi's relationship with reliability might charitably be described as complicated. The technology operates at the mercy of countless variables: wall thickness, microwave oven interference, the inexplicable whims of router placement, and the dreaded dead zones that appear to relocate based on cosmic forces unknown to science. Modern WiFi 6E has improved matters significantly, yet the phrase 'the WiFi is down' remains one of the most stress-inducing sentences in contemporary language. Studies indicate the average office worker experiences 1.3 connection drops per day, each triggering measurable cortisol spikes. Despite these shortcomings, WiFi functions continuously in billions of locations, maintaining uptime percentages that would have seemed miraculous to engineers of the 1990s.

WiFi has restructured human civilisation in ways still being comprehended by sociologists. The technology enabled the remote work revolution, fundamentally altering urban planning, real estate values, and commuting patterns. WiFi created the cafe laptop worker, the airport business lounge, and the curious phenomenon of people sitting in car parks outside closed establishments to access signals. The phrase 'What's the WiFi password?' has become a universal greeting, transcending 'hello' in certain demographics. WiFi dependency has been clinically studied, with internet addiction now recognised in the DSM-5. The technology has simultaneously democratised information access and created new forms of digital inequality based on connection quality.

Modern WiFi routers consume between 6 to 20 watts continuously, a figure that seems modest until multiplied across the estimated 1.5 billion routers operating globally. This represents approximately 15 terawatt-hours annually - enough to power a small nation. WiFi 6 introduced Target Wake Time technology, reducing device power consumption by allowing scheduled check-ins rather than constant polling. The efficiency gains are genuine: smartphone WiFi radios now consume mere milliwatts during idle states. Yet the infrastructure demands remain substantial, with data centres supporting WiFi-dependent services consuming 1% of global electricity. The technology's energy footprint, whilst improving, remains a significant consideration in climate calculations.

WiFi has achieved something remarkable in the annals of technological adoption: universal recognition without universal understanding. The distinctive three-curved-lines symbol adorns cafes, airports, and establishments across 195 nations. Surveys indicate that 78% of humans in developed nations consider WiFi more essential than hot water. Yet this recognition operates on a peculiar plane - billions demand it whilst having no comprehension of how radio frequencies at 2.4 and 5 GHz actually function. The term itself, a meaningless marketing invention from 1999, has become synonymous with internet access despite technically describing only the wireless local area network protocol. WiFi's brand recognition transcends language barriers, economic systems, and cultural divides.
