This Hacker News discussion centers around a poorly-received article (described as "AI slop") regarding SMS technology. Users criticize the article for failing to explain *how* SMS works technically and instead repeating basic information. A key point raised is that SMS pricing remains stuck in a 1990s model designed for expensive, limited-bandwidth networks. With today’s readily available and affordable data options – including satellite internet – the current SMS cost structure is outdated and doesn’t reflect actual carrier expenses. One commenter suggests a more useful follow-up would focus on the nuances of SMS delivery, specifically how different routes perform under network load and the lack of detailed delivery tracking exposed by most APIs. Several users express disbelief the article reached the front page.
