It's an inappropriate leap. Consumers should have ECC memory too.
However the consumer market has long decided to settle for ECC nowhere and cheap everywhere.
ECC hardware comes at premium option that can easily be +100%. You need support in the memory, the motherboard and the CPU.
Given the price difference, personal computers will have to live with the memory errors. People will not pay double for their computers. Manufacturers will not sacrifice their margin while they can segment the market and make a ton of money off ECC.
Amd has modestly priced hardware that supports ecc
Was that the case before Ryzen? I know their new CPUs support ECC, but I'm not sure for earlier generations.
I think it was common for AM3 for example too.

Yep.
Bristol Ridge does support ECC BTW, but one problem is that you can't use ECC with x16 chips (because ECC is 72-bit), so with 8GB of RAM and 8Gbit chips you have to choose between non-ECC/ECC single channel with x8 chips and non-ECC dual channel with x16 chips. 4Gbit don't have this problem but will become obsolete especially when 18nm ramps up, and while DRAM prices should decline when that happens...
What's the matter with x8/x16 chips and dual channel? I don't think it should matter.
Or do you mean that if you want exactly 8GB then it's hard to find a pair of 4GB DDR4 ECC modules? Well, just get 2x8GB if you are a performance nut.
Yes, what I am saying is that it is impossible with 8Gbit chips, but possible with 4Gbit.
