If my little knowledge from biology class serves me correct, RNA uses Udenine instead of Thymine. But in this document it uses T. Can somebody explain to me why?

You probably mean uracil, not udenine (which doesn't exist AFAIK).

Yeah, English is my second language. I just thought of a Translation that sounded reasonable rather than looking it up.

The Human Genome Project was completed almost two decades ago, and somebody solved the protein folding problem recently. Why are we still doing genetics at the machine code level? Shouldn't we have some compilers, assemblers and linkers by now?

I feel this XKCD describes the situation particularly well: https://xkcd.com/1831/

Why haven’t viruses or bacteria evolved to use a lipid nano particle to evade the immune system? Seems like a big security flaw in our cells?

I remember someone coming up with a song to encourage people to wash their hands more thoroughly much earlier in this pandemic. https://twitter.com/vesselofspirit/status/123748864242514739... According to the song lyric, "novel coronavirus / has a lipid outer shell". So it seems like some viruses have taken advantage of this.

Yeah I think that's the reason for the 20-30 second wash since it takes time for the soap to break down the fatty layer.

They have. That spike protein is part of their envelope ("nanoparticle").

The envelopes used in an RNA vaccine are generally simpler, because they're working under different constraints than viruses. For example, their envelopes don't need to be easily manufactured in a cell.

But some RNA and DNA vaccines do use viruses as their delivery mechanisms, eg the J&J COVID vaccine.
