It's not just the arcade machine implementation. The owners of these companies want to go all the way and move everything to data centers so they can rent compute time, similar to the idea of the time-sharing days of the 60s.
The aj function at its heart is a bin (https://code.kx.com/q/ref/bin/) search between the two tables, on the requested columns, to find the indices of the right table to zip onto the left table.
aj[`sym`time;t;q]
becomes
t,'(`sym`time _q)(`sym`time#q)bin`sym`time#t
The rest of the aj function internals are there to handle edge cases, handling missing columns and options for filling nulls.
A lot of the joins can be distilled to the core operators/functions in a similar manner. For example the plus-join is
> just like LLM agents were a new layer on top of LLMs, Claws are now a new layer on top of LLM agents, taking the orchestration, scheduling, context, tool calls and a kind of persistence to a next level.
Layers of "I have no idea what the machine is doing" on top of other layers of "I have no idea what the machine is doing". This will end well...
In this case the majority of the work was done by another company on your instruction. When you signed up was there anything in the terms that said you get ownership over the output?
Another way to look at it is everything a LLM creates is a 'hallucination', some of these 'hallucinations' are more useful than others.
I do agree with the parent post. Calling them hallucinations is not an accurate way of describing what is happening and using such terms to personify these machines is a mistake.
This isn't to say the outputs aren't useful, we see that they can be very useful...when used well.
