           | I agree. There is a lot of data people want that isn't made

             | That applies to so many other jobs.
             | 
             | My productivity as a single IT developer, making a rather
             | large and complex system mostly skyrocketed when LLM's
             | became actually useful (around GPT4 era).
             | 
             | Work where i may have spend hours dealing with a bug, being
             | maybe 10 minutes because my brain was looking over some
             | obvious issue that a LLM instantly spotted (or gave
             | suggestions that focused me upon the issue).
             | 
             | Implementing features that may have taken days, reduces to
             | a few hours.
             | 
             | Time taken to learn things massive reduces because you can
             | ask for specific examples. Where a lot of open source
             | project are poorly documented or missing examples or just
             | badly structured. Just ask the LLM and it puts you in the
             | right direction.
             | 
             | Now, ... this is all from the perspective of a 25+ year
             | experienced dev. The issue i fear for more, is people who
             | are starting out, writing code but not understanding why or
             | how things work. I remember people before LLM's coming in
             | for Senior jobs, that did not even have basic SQL
             | understanding, because they non-stop used ORM's. But they
             | forgot that some (or a lot) of this knowledge was not
             | transferable to different companies that used SQL or other
             | ORM's that may work different.
             | 
             | I suspect that we are going to see a generation of
             | employees that are so used to LLMs doing the work but not
             | understanding how or why specific functions or data
             | structures are needed. And then get stuck in hours of LLM
             | loop questioning because they can not point the LLM to the
             | actual issue!
             | 
             | At time i think, i wish this was available 20 years ago.
             | But then question that statement very fast. Was i going to
             | be the same dev today, if i relied non-stop on LLMs and not
             | gritted by teeth on issues to develop this specific
             | skillset?
             | 
             | I see more productivity from Senior devs etc, more code
             | turnout from juniors (or code monkies), but a gap where the
             | skills are a issue. And lets not forget the potential issue
             | of LLM poisoning with years of data that feeds back on
             | itself.

             | Well, yes, but fortunately, we build computers to automate
             | things using simple algorithms to remove the risk of such
             | mistakes.
             | 
             | Except when we use LLMs, in which case we increase the risk
             | of mistakes.

             | Well, Wikipedia is a great tool, but it is permanently
             | weaponized.
             | 
             | C/Assembler vs. garbage-collected languages was about
             | decreasing the risk (at the cost of increasing the resource
             | requirement), so, unless I misunderstand what you write, it
             | kinda feels like you're arguing against your side?
