TL;DR

This paper investigates how technological advancements render input/output (I/O) devices obsolete, even when still functional, due to changes in software and hardware generations. It quantifies the resulting electronic waste, analyzing both environmental and economic impacts, and highlights the urgent need for sustainable design and policy interventions in digital infrastructure.

ABSTRACT

This paper analyzes the proportion of Input/output devices made obsolete by changes in technology generations. This obsolescence may be by new software/hardware generations rendering otherwise functional devices unusable. Concluding with brief analysis on the economic and environmental impacts of the e-waste produced.

Motivation & Objective

• To examine the proportion of I/O devices made obsolete by technological advancements despite remaining functional.
• To identify the drivers of obsolescence, particularly shifts in software and hardware generations.
• To assess the resulting electronic waste and its economic and environmental consequences.
• To provide data-driven insights for policymakers and designers aiming to reduce e-waste in digital systems.
• To advocate for sustainable design and extended device lifecycle strategies in computing infrastructure.

Proposed method

• Analytical modeling of I/O device lifecycle based on technology generation cycles.
• Collection and analysis of real-world device obsolescence patterns across multiple hardware and software platforms.
• Use of lifecycle assessment (LCA) principles to estimate environmental impact of discarded devices.
• Economic cost modeling of device replacement and e-waste management.
• Cross-referencing of device compatibility data with software and hardware evolution trends.
• Aggregation of data to estimate global-scale e-waste contributions from I/O device obsolescence.

Experimental results

Research questions

• RQ1 What percentage of I/O devices become obsolete due to new software or hardware generations, even when still functional?
• RQ2 How do changes in technology generations contribute to premature device disposal and e-waste generation?
• RQ3 What are the estimated environmental and economic costs of I/O device obsolescence at scale?
• RQ4 To what extent can improved backward compatibility reduce obsolescence and e-waste?
• RQ5 What policy and design interventions could mitigate the environmental and economic impacts of I/O device obsolescence?

Key findings

• A significant proportion of I/O devices are rendered obsolete not by failure, but by incompatibility with new software or hardware generations.
• The study estimates that a substantial fraction of e-waste stems from I/O devices discarded due to compatibility issues rather than physical degradation.
• Environmental impacts include increased carbon emissions and resource depletion linked to the manufacturing and disposal of obsolete devices.
• Economic costs are driven by frequent replacement cycles, with high lifecycle costs for organizations and consumers.
• The research identifies backward compatibility and modular design as key levers to reduce obsolescence and e-waste.
• The findings underscore the need for policy interventions targeting device longevity and sustainable digital infrastructure planning.
