Yes they are very helpful. But what is the incentive to create more blogs for them LLM companies to scrape for novel tech? They are great for answering questions about things that are very well documented and understood but the incentive structure that aligns technical bloggers with search is being undermined.
In tech, knowledge scales non-linearly. No amount of trivial search can amount to finding excellent technical writing. Most of the stuff LLMs are great at answering are things that an individual can typically figure out already just much more slowly by RTFM (eg: react component, MVC code etc.) However, the LLMs fail at deeply technical or highly novel subjects.
I worry LLM usage overtime will create a gap between research papers and engineering as nobody is incentivizeded to write about their implementations/explorations.
I am hearing more and more tech-people jumping to Kagi regardless of role (SWE,SRE, PD,DS) which is encouraging.
