There is enough brainpower in the BTC pool to solve current problems.
We've had 'bitcoin is dead' stories before. (Like 86 times, i lost count) These stories seem to surface just before bitcoin surges in popularity and value.
As previously, this is a propaganda attack on bitcoin. The only thing threatened by bitcoin is the ''monopoly'' of the big banks.
It's their power and their resources which has been targeted against bitcoin. Probably it's the threats and/or bribery of the banksters that have lead to Mike Hearn's attack.
I strongly suspect that it's because bitcoin has been showing signs of steady growth that this attack is being launched against it. The point of course is to shake confidence in the currency and slow down it's growth.
We don't know the circumstances behind Mike Hearn's actions. Maybe the banksters have bribed him ore the banksters have threatened him (or his family) Ore he's just going through a rough emotional time.
"banksters" for the most part only exist in your imagination and on the Alex Jones show.
(And if they do exist, they putting senators in their pocket, not programmers of open source projects.)
