California’s “Safe and Secure Innovation for Frontier Artificial Intelligence Models Act” (a.k.a. SB-1047) has led to a flurry of headlines and debate concerning the overall “safety” of large artificial intelligence models. But critics are concerned that the bill’s overblown focus on existential threats by future AI models could severely limit research and development for more prosaic, non-threatening AI uses today.

SB-1047, introduced by State Senator Scott Wiener, passed the California Senate in May with a 32-1 vote and seems well positioned for a final vote in the State Assembly in August. The text of the bill requires companies behind sufficiently large AI models (currently set at $100 million in training costs and the rough computing power implied by those costs today) to put testing procedures and systems in place to prevent and respond to “safety incidents.”

The bill lays out a legalistic definition of those safety incidents that in turn focuses on defining a set of “critical harms” that an AI system might enable. That includes harms leading to “mass casualties or at least $500 million of damage,” such as “the creation or use of chemical, biological, radiological, or nuclear weapon” (hello, Skynet?) or “precise instructions for conducting a cyberattack… on critical infrastructure.” The bill also alludes to “other grave harms to public safety and security that are of comparable severity” to those laid out explicitly.

In the summers of 2018 and 2019, ecologist James Ryalls and his colleagues would go out to a field near Reading in southern England to stare at the insects buzzing around black mustard plants. Each time a bee, hoverfly, moth, butterfly, or other insect tried to get at the pollen or nectar in the small yellow flowers, they’d make a note.

It was part of an unusual experiment. Some patches of mustard plants were surrounded by pipes that released ozone and nitrogen oxides—polluting gases produced around power plants and conventional cars. Other plots had pipes releasing normal air.

The results startled the scientists. Plants smothered by pollutants were visited by up to 70 percent fewer insects overall, and their flowers received 90 percent fewer visits compared with those in unpolluted plots. The concentrations of pollutants were well below what US regulators consider safe. “We didn’t expect it to be quite as dramatic as that,” says study coauthor Robbie Girling, an entomologist at the University of Southern Queensland in Australia and a visiting professor at the University of Reading.

After SpaceX decided to launch orbital missions of its Starship rocket from Texas about five years ago, the company had to undergo a federal environmental review of the site to ensure it was safe to do so.

As a part of this multi-year process, the Federal Aviation Administration completed a Final Programmatic Environmental Assessment in June 2022. Following that review, SpaceX received approval to conduct up to five Starship launches from South Texas annually.

SpaceX has since launched Starship four times from its launch site in South Texas, known as Starbase, and is planning a fifth launch within the next two months. However, as it continues to test Starship and make plans for regular flights, SpaceX will need a higher flight rate. This is especially true as the company is unlikely to activate additional launch pads for Starship in Florida until at least 2026.
