Microtubles aren't made from RNA, and your techy analogy seems incredibly forced to me.
At some point in cybernetic convergent evolution almost in parallel with the technological singularity, there will be IT architecture problems that will need to be addressed, and people on HN will bikeshed if square auxiliary optic nerve connectors or triangular ones are better. Just imagine being hellbanned for bringing-up circular ones, and no one else is able to interact with you. Eeek!
Yes they are. They are proteins. Proteins are made from DNA->RNA->ribosomal transcription.
Also microtubules interact with RNA quite a lot. Check the references: https://pubmed.ncbi.nlm.nih.gov/15037309/
