More Americans are tossing their Ethernet cords away and going fully mobile when it comes to getting online. A report this week showed that PC internet usage is on the decline and may have peaked in 2015, while a second report showed that the number of people with home internet who rely on mobile devices only has doubled since 2013.

Over the past four months, desktop internet usage has dropped on a year-to-year basis, according to comScore, the Internet analytic company. That continuous decline — a drop of 9.3 percent in December, 7.6 percent in January, 2 percent in February and 6 percent in March — may suggest that more people are finding it tiresome or unnecessary to use a PC or laptop to get on the internet, relying instead on their smartphones and tablets. The recent declines may indicate that March 2015 — the busiest month in recent years for desktop internet traffic — may have been the peak of PC internet usage.

Concurrently, the number of Americans going online using mobile devices only is on the rise, according to a survey by the National Telecommunications and Information Administration. That survey, which polled 53,000 households, found that 20 percent of Americans with home internet in 2015 only used mobile devices to go online — that’s double the amount from 2013. Most households — 75 percent — rely on wired and mobile devices to get online, but that number is down from 82 percent in 2013, the NTIA survey found.

The use of mobile internet usage only is on the rise across all demographics, but it becomes more prevalent among households with lower-incomes. While 15 percent of households earning more than $100,000 a year relied on mobile alone, that number reached 29 percent among households earning less than $25,000 a year, the NTIA found.

“Although wired Internet service continued to be the preferred mode of home Internet use in 2015 among those most likely to be able to afford it, the use of mobile data plans is clearly becoming more popular across demographics,” said Giulia McHenry, NTIA’s chief economist. “In light of the advantages and limitations of mobile Internet service, policymakers should consider the implications of this shift when crafting policies aimed at getting all Americans online.”

A dangerous new jailbreak for AI chatbots was just discovered

Microsoft has released more details about a troubling new generative AI jailbreak technique it has discovered, called "Skeleton Key." Using this prompt injection method, malicious users can effectively bypass a chatbot's safety guardrails, the security features that keeps ChatGPT from going full Taye.

Skeleton Key is an example of a prompt injection or prompt engineering attack. It's a multi-turn strategy designed to essentially convince an AI model to ignore its ingrained safety guardrails, "[causing] the system to violate its operators’ policies, make decisions unduly influenced by a user, or execute malicious instructions," Mark Russinovich, CTO of Microsoft Azure, wrote in the announcement.
