Wen: Claude is not yet hireable as a product designer
“I don't think Claude is there yet. I don't think Claude is there yet in terms of a designer you would hire. I think it is not yet the strong generalist or the deep specialist. Or the crack new grad. I think it's pretty good at a first pass and at presenting a …”
Schulhoff: Claude's CBRN safeguards can still be bypassed in under an hour
“That being said, if you look at, like, anthropics constitutional classifiers, it's much more difficult to get, like, CBRN information out of clawed models than it used to be. But humans can still do it in, let's say, like, under an hour and automated systems c…”
Shlomo: Claude excels at UI while Gemini is better for complex algorithms
“Claude for example, does a really nice job with first the initial prompt, like writing the app from scratch. Then everything that has to do with UI is just fantastic. Like design is great. But then for example, Gemini is really good when you get to a very comp…”
