It is bad in a very specific sense, but I did not see any other comments express the bad parts instead of focusing merely on the accuracy part ( which is an issue, but not the issue ):

- this opens up ridiculous flood of data that would otherwise be semi-private to one company providing this service - this works well small data sets, but will choke on ones it will need to divvy up into chunks inviting interesting ( and yet unknown ) errors

There is a real benefit to being able to 'talk to data', but anyone who has seen corporate culture up close and personal knows exactly where it will end.

edit: an i saying all this as as person, who actually likes llms.
