Enjoyed reading the thoughts either way.
I don't know all the details of how PPC functions, personally, but at this point, they all reduce rewards without consideration for actual individuals. That is why they all end-up depending on pools for any kind of fractional reward.
They decay based on hash-power, fast, leaving the only real rewards for early miners.
Eg, 1 miner gets 10 a day early on, solo-mining... then a month later, gets only 1 a day... then a month later the reward is 1 every 10 days... then ultimately, it takes 1000 miners to get 1 coin a month, which they all have to split 1000 ways. (As the network grows from 1 to 10 to 100 to 1000 to 10000000 miners {miners hardware})
To the comment about PrimeCoin and other forms of "do something" coins...
Just replacing "scrypt" or "sha256(sha256)" with "solve another solution"... I do not personally see as a "generation upgrade". That is just a swap of "solutions". (But like I said, I have mixed feelings about that feeling.)
IF they rewarded YOU, in coins, for that work... (Coins they had to purchase to get those results). That would be a generation-3 coin. However, finding a cure for cancer, by burning power (coal/nuclear/hydro) and using Chinese manufactured circuits that contain more cancerous elements and cause more cancers than they solve... that only rewards "pharmaceutical companies trying to save millions and making you spend millions and then use that solution to charge you for a cure"... I don't quite see "That" as being a gen-3 coin. However, it is better than the "do nothing" for a coin. That I agree with.
By the way...
Cancer has no cure... Nothing actually has a cure. That is just false advertising. That is how they manage to sucker people to give them money, so they don't have to spend it creating "ailment alleviations", that they call cures. If you had cancer in your body, and you "cured it"... that would leave your insides looking like swiss-cheese, full of holes where the cancer previously lived. Even if they found a cure, they couldn't cure you until you got it... and that would kill you, curing it.
Name one thing that was ever cured? You can't. Because nothing has ever been cured, only delayed, hidden, masked, subdued, or made worse... TB, Polio, Syphilis, Chicken-pox, Cow-pox, Small-pox... They all claimed to have a cure, they simply created more deadly versions in the process. The cures kill more people than the actual ailments ever did, and it only cost us trillions every year, for them to find new ways to kill us!
You want to cure cancer...
Stop buying cell-phones, stop listening to the radio, stop sitting next to a wifi computer, disconnect your RF power-grids, move away from the city, stop ingesting toxins, stop washing your clothes with cancerous bleach that you sit-in all day long, and move away from the radiation-screen blasters that you are reading these words on...
Oh, and stop breeding with people who are prone to cancers. Get to know the mother, father, grandmother, grandfather of the person you mate with, before you spawn genetic variations of undesired traits.
Problem solved... but no coins earned... and you CAN afford that cure!
Harsh, but true... We all start to die, from the second we are born. Some just do it better, more efficiently, peacefully, and willingly, more than others, who normally go out kicking and screaming, like they way they arrived in the world. In the end, we all just make things worse for those entering the world, before we exit. Even if we lie, and tell ourselves it is better... it is not. Thus, we offer only ailment alleviations, to those who pay us the most, the rest just have to suffer.
I enjoyed your first post... you should have stopped there.
