The 2010s witness the dominance of cloud-based productivity tools, enabling seamless collaboration and accessibility from anywhere. The integration of artificial intelligence and automation into productivity tools aim at streamlining tasks and providing personalized assistance. Towards 2020, the COVID-19 pandemic accelerates the shift to remote work, emphasizing the importance of digital collaboration tools and flexible productivity solutions. Finally, the rise of large language models, like GPT-3, further increase productivity. These models automate tasks, generate content, and assist in various applications, streamlining processes and enhancing efficiency across industries.
