Back to my original concern: has the certification process for the 787 so far proven to be adequate?
The short answer is: YES.
But if you can read English I suggest you dive into this report, it is long and very thorough, it compares 787 with similar aircraft in their initial stages of operation, it uses numbers (some nice graphs) not forums slogans, it addresses certification issues, quality control, redundancies, design architecture, outsourcing, etc. It has nothing on batteries as there will be a separate report about it.
