Many existing technologies and processes will crack under the change.

INTERPOLATIVE SOFTWARE

Interpolative software is code that is solidly within the training distribution of models. It can often be specified with just a few sentences of prompting. Novel software is something that has fundamentally not existed before. Writing novel software with agents is challenging, as they are not trained on the task. Not a lot of software is novel, which is fine, as there is still a ton of value in the interpolative stuff.

However, schools that choose to restrict AI entirely will also lose access to Google search. Google had earlier turned on AI features as the default option and is claiming that the reversal is in response to feedback from educators and parents. The company's decision to use this strategy shows how much power it has over the US education system.
