OK, there is no private key for these bytes, because public keys start with 0x04, 0x03 and 0x02

Why do you say there is no private key for the bytes? Can you elaborate the reason?
My guess is that those coins are possibly recoverable unless the person who sent the puzzle is a sicko :)

1000 satoshis is very less, affordable amount to lose so its possible that the coins went into a blackhole.. But I think this is unlikely.

A public key in Bitcoin is a point on an elliptic curve.  It must be encoded either as two coordinate 04+x coord + y coord or as parity plus x coordinate.  If it is not in this form the script always fails, which means it is unspendable.  In this transaction the public key is the string "find...satoshis", which doesn't start with 04 and doesn't lie on the elliptic curve.

It would be funnier if they had at least used a point of the form 02 + "32 byte string" and made sure that the point is really on the curve.  Extra points if they managed to spend it :)

BTW, this joke is now permamently in the UTXO list of every full node, which means it takes a little bit of RAM on every full node for the next centuries.  This is why these kind of spam is not liked so much.

It is provably unspendable. Nodes can treat this output like OP_RETURN
(OK, this check is not in current consensus code)
which means it takes a little bit of RAM on every full node for the next centuries.  
Centures? Are you joking? No doubt that bitcoin will die earlier :) I think - this year

Bitcoin is here to stay! There is no Bitcoin is dead; it's more like: Bitcoin is always on the verge... and its disruptive power is already entrenched!

So, after bitcoin's death which ALT will rise according to you ? ::)

It is difficult to predict the behavior of the crowd that have little understanding of the technology and operate on a whim.
Most likely there is a desire to move to PoS
But PoS is not much different from the traditional currencies

Well, when bitcoin rises to, lets say, 10m$/BTC probably it will be not "very less".

10m$/BTC?  I would like to bet 10m$ that it won't get to 10m$/BTC  ;D

Deal.
Are you ready to deposit your bet amount today?  ;D

That's sad. Will it be possible in the future for nodes to not accept such bad transactions?

You can make a patch to Bitcoin Core that checks outputs validity.
You can submit this patch to master code branch.
Everyone can use your patch or not use it.

So, the answer is: yes, it is possible to reject such transactions (before confirmation in block and even after in case of fork).
But there is no significant reasons for anyone to change current clients behavior.

So basically one is playing tricks with another over a small amount? This can be easily claimed at some faucet (no names given)

What happens when what started out as a respectable thread turns into a is-crypto-ded troll show?

This.

In the "strict sense" nothing it is forever fortunately or unfortunately. But Bitcoin will stay for some years at least same time that "Internet era", As we know.

10m$ is 1 cent btw,
Or did you mean 10 mega$, in which case it's 10M$ and a shitload of money. :)

I keep clicking on this thread and expecting to see something starting "I'd tell you a blockchain joke but..."

Can someone help out with the punchline?

This thread has converted to bitcoin price discussion thread. Nothing to see here.

ok, here's one...

how many bitcoin devs does it take to screw in a light bulb?

possibly just one, but it takes 5 hours and at least 6 confirmations to actually light up
