Impact of technology on society

Technology is the application of scientific knowledge, tools and techniques to solve practical problems and make life easier. It changes how people live, work, communicate and think, with both benefits and harms.

Positive impacts

• Economy and production: machines, automation and ICT raise productivity and create new industries and jobs (software, telecom, hydropower).
• Communication: mobile phones, the internet and social media connect people instantly; remittance, e-banking and online services reach remote areas.
• Health: vaccines, diagnostic equipment and telemedicine increase life expectancy and reduce infant mortality.
• Education: e-learning, online libraries and virtual classes widen access to knowledge.
• Transport and infrastructure: roads, bridges, airports and vehicles cut travel time and boost trade.
• Comfort and living standard: electricity, clean water supply and household appliances.
• Governance: e-governance, online tax and citizen services bring transparency.

Negative impacts

• Unemployment due to automation; a widening gap between technology-rich and poor groups (digital divide).
• Environmental damage: pollution, e-waste, climate change, deforestation.
• Loss of privacy, cyber crime, fake news and screen addiction.
• Weakening of traditional skills, culture and face-to-face relations.
• Weapons of mass destruction and accidents from technical failure.

Changes in the 21st century

• The internet, smartphones, cloud computing, AI, IoT and big data have made society information-driven.
• Work from home, online shopping, digital payment and social networking have become normal.
• Globalisation: knowledge, goods and labour move across borders quickly.
• New concerns: data security, ethical use of AI, sustainable development and green energy.

Technology is a tool; its effect on society depends on how responsibly engineers and users apply it.
