Edit: I do plan to get the vaccine, but as a software engineer I know beta versions usually have the most “bugs” — and I have the health privilege to be in the back of the line so I will!
On the other hand, if you want to read about how software works when it actually matters, "space shuttle coding style" is fascinating.
If there's autoimmune issues that pop up when the scale goes from tens of thousands to hundreds of millions, I'll know about it ahead of time and be able to take the appropriate action, such as choosing a non-mRNA vaccine such as the adenovirus type from Astrazeneca.
Vaccines are not 100% effective but they don't have to be. The goal here is to reduce transmission in the population to a level where the virus can no longer spread. That is only possible if enough people take the vaccine and healthy people should absolutely be in the front of that line.
This is not a purely personal choice. You have to understand that by deciding not to immunize yourself you are making a decision for everyone else.

It cannot be ruled out that the whole concept of RNA vaccines still has bugs, but it is nowhere near "it compiles, ship it now!" software betas. The process is much more risk-averse.
If I want to use your printer (ribosomes) to print out some stuff (proteins), I don't need to send files (genetic instructions) to your computer (nucleus). I can just get on your wifi, send my files directly to your printer, and go home. Except I accidentally left the protein at your house. But none of the genetic material sticks around.
