Counterpoint: Putting a PC on every middle-manager's desk destroyed the typing pool. Typist was a skilled trade, and replacing the typing pool with a PC and word-processing software cost those jobs, and it cost managers time because dictation to a skilled human is faster than hunt-and-peck typing into Microsoft Word or the like, and it reduced the quality of business prose because it was no longer trained professional writers producing the final copy.
There have been a number of studies which suggest the "PC revolution" was actually fairly expensive in terms of productivity.
On a similar note, giving spreadsheet software to bookkeepers and others who understood how to use paper spreadsheets was productive. Giving them to people with no idea how to use them correctly? Quite possibly not.
A CACM article on the 20th anniversary of Powerpoint (which presumably was published around 16 years ago, but I'm not going to go look for it) noted that in the '80s, similar presentations were generally either B&W overhead transparencies1 or carefully-orchestrated multimedia presentations with synchronized slide projectors and tape decks that took many hours to create. Now Powerpoint Rangers generate zillions of fancy presentations every day with graphics! and animation! and mind-numbing stupidity! – which, yes, is a lot more output, but is it more value?
And I recall a Byte article from many years ago (obviously) about the "Fat Bits" option in Mac Paint (or whatever it was called): the zoom function, basically. The author suggested that having a zoom function, and being able to do pixel-by-pixel editing, led to people wasting a vast amount of time fiddling with details that no audience member was likely to notice, and thus offered essentially no return on investment.
Information technology has severe revenge effects, especially when it attracts a lot of attention2 and triggers obsessive behavior in users.

2One of the great ironies of the current LLM fervor is that it was touched off by a paper titled "Attention is All You Need". The use of "attention" as a term of art in transformer algorithms is an accidental gesture toward the greatest problem they currently cause.
