It shows how vaccines that educate the immune system against one enemy may inadvertently help it fight others. For humanity, that implies that what is learned during a worldwide health crisis may go on to save lives in ways unforeseen.

regardless of their tumor type. If it holds up in clinical trials, this discovery could fundamentally change the way cancer is treated everywhere. By linking mRNA vaccines to existing immunotherapies, doctors might be able to strengthen their patients' immune defenses without having to use

while I am very skeptical of "AI"-hype and don't expect tech giants to have anyone's best interest in mind, I do think we did some things well in this project, so keep these three things in mind >

Will try to gather in this thread some steps I'm taking to put me in a better position to be an effective "AI" critic at my EdTech company. See quoted thread for a bit of context
calling all #AI haters (complimentary): I participated in a project evaluating LLM-supported math tutoring and would love some criticism/references/whatever you've got that might influence follow-up projects.

outcomes, ensuring that whatever system we put out there does in fact improve children’s maths knowledge.

So all in all I'm cautiously proud of this experiment and trying to take the time before whatever is next to sharpen my criticisms and be able to advocate for ethics as much as possible. Help!

2: Built-in accountability and recourse: Human tutors were ultimately responsible for each message sent to a student, even when the message was completely generated by the LLM. This means children always had recourse in the form of an >

1: the use-case was constrained and contextual: Instead of unleashing a chatbot to “revolutionize learning” in general, we tested a specific application where the core structure was not stochastic. After answering a diagnostic question incorrectly, students were routed to a tutor chat meant to >
