I somewhat agree but would think it depends on what part of "mining" they are doing and what they do with their free time when the mining does not need upkeep.

The ones developing chips and software around digital currencies most likely won't experience any skill loss.

Clouds have faded away and the 89949%(00:00:24 duration) block was confirmed, lets hope another storm doesn't roll through. 

I've always wondered how that works for blocks that take around a minute or less after the previously found block.

Just found two blocks, hoping they stick!

One had 89949% Luck?

Over time can we expect many users to have lost BTC due to similar issues (bringing the total BTC available to less than 21mil) and they would not be recoverable by anyone?
