Non-SWE person here. In the past year I've been able to use LLMs to do several tasks for which I previously would have paid a freelancer on Fiverr.
The most complex one, done last spring, involved writing a Python program that I ran on Google Colab to grab the OCR transcriptions of dozens of 19th-century books off the Internet Archive, send the transcriptions to Gemini 1.5, and collect Gemini's five-paragraph summary of each book.
If I had posted the job to Fiverr, I would have been willing to pay several hundred dollars for it. Instead, I was able to do it all myself with no knowledge of Python or previous experience with Google Colab. All it cost was my subscription to ChatGPT Plus (which I would have had anyway) and a few dollars of API usage.
I didn't put any full-time SWEs out of work, but I did take one job away from a Fiverr freelancer.
