“There’s going to be a fundamental rebalancing in terms of how we think about indoor spaces," Allen says. "I think people won’t tolerate sick buildings. That era is over. Rightly so, and good riddance.”.#HealthyBuildings.

Remembering the time @NateSilver538 bet me $1M that it was not 100% that, in 10 years, electric vehicles would be safer than human-driven cars (I pay him $1M, he would pay me $10k.) I would’ve done it but didn’t think he’d be solvent in 10 years to pay me the $10k b/c of his.

It seems like there is not enough of a policy response to the fact that, with 57M miles of data, Waymo’s autonomous vehicles experience 85% less serious injuries & 79% less injuries overall than cars with human drivers. 2.4 million are injured & 40k killed in US accidents a year.

More meddling in business. “nearly 70 percent of the turbines have been installed. The developers behind the project had said it was on track to produce enough electricity for more than 350,000 homes in Rhode Island and Connecticut by next spring.”

Stopped in on way to airport to see what all the fuss was about. Took them 28 minutes to make a breakfast sandwich to-go. I don’t think the logo is the problem. (I like the old one, FWIW)

I come across so many academic scientists who do not want to revisit standards and thresholds as the science evolves. It’s bizarre to me. So many are happy w status quo, even when, as in this case, the status quo is based on some pretty shaky footing….

Urban #wildfires in LA put kids at risk from #lead‑contaminated soil. Authors urge mandatory post‑cleanup soil testing & cutting California’s safety standard from 80 to 55 mg/kg to better protect families. Time to update wildfire recovery policies!.
