I guess you'll have to wait for a long, long time... IIRC, he dissapeared about 10 years ago and nobody has heared from him ever since... I doubt he'll see your message and think "hey, this guy is right... I'll just re-appear after 10 years to make a new currency".

As for your theory that changes or forks mean a failed coin: i can't say i agree... Changes are made to fix bugs, to add new features, to adapt to changing conditions, to increase troughput, to decrease load... Fixing something (even if it means forking) is not equal to failing.

My wife is driving a Toyota Yaris that i bought about ~8 ish years ago... If i compare my car to the new Yaris, i can see the new model has a lot of new features... Some of them are safety related, some comfort related, some environment related... This does not mean my old Yaris was a failure: at the time i bought said car, it was an "average" car with "average" state-of-the-art features. Just because somebody found new safety features, or people's taste changed so they had to adapt the looks of the car, or the environmental rules changed didn't make my old car "bad"....
