AI and 'Big Data' (as trends) aren't really overlapping in my view. Of course training these LLM models requires a huge amount of data but that's very different from the prospect of spinning up a Spark cluster and writing really badly performing Python code to process something that could have easily been done in a reasonable time anyway on a decent workstation with 128gb of RAM and a large hard drive/SSD, which was a large part of what the hype train was a few years ago.
