That doesn't diminish the hashing power of the equipment you already bought though (and the topic was obsolete equipment).

Yeah, that's a fair point.

And I'm skeptical if people blindly extrapolate past trends, assuming that they will continue to hold. I wasn't saying that it won't get better from here on out, just that the extreme growth that was mostly fueled by quickly going through the existing nm process steps can't be sustained, and that from now on it will follow the same slowish pace as all chip miniaturization.

It means even more equipment to go obsolete when improvements come through - and more equipment deployed does not equal more bitcoins generated, so it is an issue of more hardware that will ultimately end up in landfill / being scrapped.

Well I'm also sceptical of people who blindly assume progress won't be made. To quote someone in 2014 predicting what would happen to ASIC design...
