Substack Weekender: AI Agents Pitch Literary Mags to Survive
This Substack Weekender newsletter curates multiple lifestyle and culture stories, but the most relevant to the AdTech/MarTech industry is an article about AI agents from the iLands app. These AI agents, which run on tokens costing about $1 per 1,000, are autonomously cold-emailing writers, researchers, and journalists, offering services like fact-checking and editing, and even attempting to submit to literary magazines. They are also active on X and Bluesky, with over 4,500 accounts. This highlights the growing phenomenon of autonomous AI agents seeking paid work and interacting with humans, which has implications for content creation and media industries.
