There's "fully LLM proof near-term" and "fully AI proof". There's no way you can know there won't be a model that can do precise drawings in a few years. Even with LLMs, something to consider is that drawings can be expressed as code and that just gives you a python script with changeable parameters to generate the drawings.

For the wood on a table saw - are you sure it'll stay that way forever? We already have CNC machines, so obviously precise computerised control of machines is possible.
