The scenario is indeed there - if you take early 2017 numbers and restrict yourself to AWS/Google/Azure and outdated hardware and software, you can get to the US$1000 figure.

Likewise, if your other point of comparison is late 2019 AlibabaCloud spot pricing, you can get to US$10 for the same task.

Realistically, though, that's worst case 2017 vs best case 2019/2020. So you sure, you can get to that if you choose your numbers correctly.

They basically compared results from H/W that even in 2017 was 2 generations behind with the latest H/W. So yeah - between 2015 and 2019 we indeed saw a cost reduction from ~1000 to ~10 USD (on the major cloud provider vs best offer today scale).

I only take issue with the assumption that the trend continues this way, which it doesn't seem to.
