Biased and non-impartial view.
Mike Hearn was pulled away from the core development team for Bitcoin, by none other than the banks. The banks fear Bitcoin due to its low running cost, instant transfers Internationally and complete decentralisation, which in turn means, no need for banks.
So is it a surprise that Mike Hearn is now singing the song of the banks i.e. Bitcoin is doomed, it is "inescapable", no way back etc.
No, this is not the case.
Bitcoin is code, it can be changed, updated, fixed and made better.
The real problem with Bitcoin are the non-incentivised nodes, or in simple terms, there are no rewards for maintaining the networking by running a Bitcoin node. You don't get paid, it only costs money. Because of this, the total node count has been falling, this is far more of an issue than the blocksize will be. Again, this can also be fixed, if the Bitcoin community want it and if the core development team make it happen. But this will be a test of how "centralised" the development team and Bitcoin has become and whether the community does have a say or if the shots are simply being called from the Bitcoin core development team.
Time will tell.
