Nothing you mentioned is an inherent problem with the databases. In fact, databases have arguably more potential to solve these problems then any currently used system. Like debugging - if every memory access is a database access, then you have a builtin logging for all your memory access that is both more performant and optimal then any normal normal debugger. You can take snapshots of your 'memory' pretty much at any time, the data layout is clearly defined. You can manually edit your memory any time you want, and serialization is already solved for you. The more I think about it, the more possibilities I come up with. Damn, this is actually genius!
