I will try my best to write a good one.

berkeman, I do not expect from you anything constructive, unless you are forced to do it. There are other people at this forum who can judge that proposal. As for the analogy, I think I just have to add one more sentence to complete it. Not only objects cannot be copied directly by using copiers...

I see forums such as this one as grassroots scientific projects, which however can be better connected with academic institutions, than an anonymous individual, who lacks academic credentials. Although I have an academic degree, I never submitted a paper in a scientific journal, and I do not...

By dummies I meant me, not you …

OK, I think we can agree that we are here at the frontier of human knowledge, unlike majority of other threads in this particular forum. Would it be preposterous then to ask all science advisors resident at this forum, and finally Marletto herself to join us, and explain her contribution to...

std::bad_alloc is not a "value that is returned" in that case, it is an "exception that is thrown/raised/whatever verb appropriate" in that case, these are two different things. Actual value returned is nullptr, and when you print it, you might get, I don't know what exactly, perhaps 0. But what...

If "new" returns 0, it probably means that the allocation failed, and no memory was allocated.

I mean, do they publish only the polished paper, or can I see somehow the whole process of proofreading? And it is not like I do not trust or appreciate your judgement, I would just like to have a second opinion from those whose academic assignment it was.

I wonder what did those who critically reviewed her paper see, what were their objections, and how she responded. I did not understand your response with respect to how can I access that info from the same page where the paper was published.

Yes, thanks, obviously “universal” is a completely misplaced attribute here, and that is entirely my mistake. They can build everything within the repertoire of the language for describing automata unambiguously, using the raw material prescribed by that language as building blocks in that...

If I put aside the proof and focus on the result, what it actually tells us is this: universal scanner of objects is impossible universal copier of objects (apart from those objects which present descriptions of other objects) is impossible universal copier of descriptions of objects is...

Part of Von Neumann's genius is that I understand perfectly every sentence of his paper. For example, the consideration about how copier works: if it consumes the instance of replicator it was presented with during the process of copying, it has to produce two instances of the replicator in...

And of course, I am not questioning if it is really so, that the replicator-vehicle is the only possible physical implementation of accurate self-reproducing automaton, I just ask if this was proved rigorously, in your opinion.

I do not know if it is vacuous, but it certainly is not very explanatory to prove that something is possible, something that we already know it exists, for more than 50 years. Basically, the discovery in molecular biology was a proof that Von Neumann's second model was realistic. However, that...
