As a follow-up to [Dot is no longer my friend. What can I do? (10h SVG Render Process) - #23 by oliversalzburg](https://forum.graphviz.org/t/dot-is-no-longer-my-friend-what-can-i-do-10h-svg-render-process/3062/23), I decided to document part of my project in English for a wider audience, and posted it on my blog.

Here is one important quote:

> To be absolutely clear, any attempt to build a time machine like in fiction, **must** fail. We can prove that scientifically. If you only _imagine_ building a true time machine to check tomorrow’s lottery numbers, you already caused the project to fail. We can not build a true time machine unless we respect these principles. But by respecting them, we inevitably set us up for results that are so profound that we **must not** have ever expected them.
