Edit: I'd prefer my biostuff data to stay mine and not be saved in multitude cloud piñatas...
Although the article does not mention it anywhere, I thought such repetitive byte sequences could be compressed quite well with simple file compression. Went digging again. I was wrong, compression of FASTQ genome sequence files IS a thing: https://en.wikipedia.org/wiki/FASTQ_format#Compression
By the time any real analysis is done on these data, they're extremely compressed via other file formats that extract the important signal. Alignment data is stored in BAM/CRAM [1], [2] formats, and variant data in VCF [3]

I don't need an AI eugenic death squad coming after me in 20 years.
500 hundred (50,000) may still be low.
(The 1000$ figure you're citing is probably benchmarking against 30x coverage, so 1k for 100x is a pretty good price.)
