I don't know. I used to agree with this, but after the umpteenth time of Claude recommending some obsolete or dead old library, old version, getting major version breaking changes dead wrong, writing code for it that's not even API compatible with the published docs, etc... I started to question whether it was actually faster. I end up pouring over the original documentation anyway.
I have learned some new things, been exposed to some new techniques, and learned about some new libraries, so it's hard to tell.
The problem is made worse by so much of the internet being AI slop now, traditional searching is a huge time waste too.
Looking forward to the next chapter of tech where we're able to use these tools appropriately and not destroy everything of value with them.
