Mr TIFF

Author John Buck chronicles his quest to credit inventors behind technology, notably Stephen Carlsen, creator of TIFF. Despite initial anonymity, Buck’s persistence led him to Carlsen, who shaped the standard while at Aldus. Tragically, Carlsen passed away before full recognition could be achieved. Buck updated TIFF’s Wikipedia entry, giving Carlsen the acknowledgment he deserves: “created by Stephen Carlsen, an engineer at Aldus.”

How to Speak to a Computer

, ,

Joseph Weizenbaum created ELIZA in 1964, an early chatbot simulating therapy by reflecting users’ statements. Unexpectedly, users grew emotionally attached to ELIZA, projecting human traits onto it. Fast forward to 2022, OpenAI’s ChatGPT made AI accessible, rapidly gaining over 100 million users. Now, chatbots serve complex roles including romantic partners and therapists, prompting ethical considerations. The history of AI spans symbolic and statistical approaches, leading to today’s language models, which are statistical products of vast datasets rather than explicit rules. Metaphorical interfaces, such as the desktop metaphor for personal computers, enhance user understanding of technology. ChatGPT leverages conversation as its guiding metaphor, allowing intuitive interaction with AI.
