Even the sameness of an electron, mentioned by the author, is at least questionable. Below is a quote I pasted in the Holographic post, which seems to support (still) in current quantum physics work the notion that an electron is unable to be ultimately defined. How can one say therefore they are the same?
It also talks of atoms consisting of "an assembly of particles enabling internal degrees of freedom." Freedom doesn't sound too fixed and "same" either.
Sameness is boring, diversity is endlessly interesting. Ain't it wonderful!
"Researchers have shown in the last few years that for photons and atoms - and now, electrons - "both/and" and "either/or" exist side-by-side. In other words, there is a grey zone of complementarity. There are hence experimentally demonstrable conditions where matter appears to be both a wave and a particle. These situations can be described by a so called duality relation. It can be viewed as an extended Complementarity Principle for quantum physics; which should be more precisely called a Co-existence Principle. It states that manifestations of matter which would normally be mutually exclusive - e.g., local and non-local, coherent and non-coherent - are indeed measurable and make themselves evident, in a particular "transition regime". One can speak of partial localisation and partial coherence, or partial visibility and partial distinguishability. These are measurements that are connected to each other via the duality relation. In this transition regime the Complementarity Principle, and the complementary dualism should be extended to the more general Co-existence Principle, describing the parallel dualism of nature. Nature has thus a more ambivalent character than previously recognized. Atomic interferometry provides us with examples of this ambivalence. It was first found in 1998 in atoms, (5) which consist of an assembly of particles enabling internal degrees of freedom."
