WiFi
WiFi technology has demonstrated remarkable evolutionary durability since its introduction in 1997. The protocol has progressed through multiple generations—from the original 802.11 standard offering 2 Mbps to the current WiFi 7 specification theoretically capable of 46 Gbps. This represents a 23,000-fold improvement in 27 years.
However, individual WiFi equipment shows considerably less resilience. The average consumer router has a functional lifespan of 3-5 years before succumbing to heat degradation, firmware obsolescence, or what technicians refer to as "just not feeling like it anymore." Enterprise equipment fares better but requires regular replacement to maintain security standards.
The WiFi Alliance projects that the technology will remain relevant for at least another two decades, though they also predicted widespread adoption of WiMAX, so their forecasting record is mixed.
Monday
Monday has proven to be one of the most durable constructs in human civilization. The seven-day week, with Monday as its perpetual returning champion, has survived the fall of Rome, the Black Death, two World Wars, and the complete restructuring of global commerce. Archaeological evidence suggests that Monday-like phenomena have existed in some form for over 4,000 years.
Unlike technological systems, Monday requires no maintenance, upgrades, or support infrastructure. It operates on what physicists describe as "pure temporal inevitability." Attempts to abolish Monday—including the French Revolutionary Calendar's 10-day week—have uniformly failed, with Monday returning stronger each time.
Futurists predict that Monday will outlast not only WiFi but potentially human civilization itself. Long after the last router has powered down, Monday will continue arriving, indifferent to whether anyone remains to experience it. This is what scholars call "calendrical permanence."
