Have we destroyed the Satoshi coins yet? Just checking...
I've seen some recent discussion of such.. ..
Whoever came up with that....

Dumb idea...
If he really wanted there to have been confidence in the economics of a deflationary currency he ought to have done it himself. The fact he didn’t leads one to believe he wants the dough. And I suppose he’s entitled to it. Either way it’s an ungodly hoard of coins that’s impossible to ignore.
I don't think that's what the discussion is about.
At some point old pubkey coins might be easily hackable. At that point, millions of BTC can be looted for the lolz by those having the tech to do it. The question is what can you do about it so that they can be moved to safety, locked, etc. Otherwise you'll have millions of BTC looted AND a PR fiasco like "ohhh Bitcoin got HACKED AND PEOPLE LOST THEIR MONEY!!! ITS UNSAFE, RUN FOR YOUR LIVES". So you have hackers dumping, people panicking, etc etc. It's a complex issue.
Wouldn't vastly more coins be in danger than just those ones in this scenario?
No, the early coins (not just Satoshis - all of the coins) use an obsolete scheme that hasn't been used in years. Essentially they don't have addresses, like now, but naked/exposed public keys.
Quantum computers can reverse a public key as long as they know it. Our modern addresses use hashes so you first have to reverse the hash, find the pubkey and then break the pubkey/privkey to access the funds. This is way more quantum-proof, as long as you don't reuse addresses (and thus expose your pubkey for long periods of time).
Much better than my response...
