Now that you mention it, are there laser etching or engraving tools that may be available outside of industrial applications should one want to record their silly thoughts in a more permanent form?

They're not cheap, but you can definitely get a very capable laser set up nowadays that you could etch a non corrosive material with. Some are pretty cool and even are able to etch curved surfaces rather easily on the user end.

Doubt laser could etch deep enough to survive wear and tear for thousands of years.

I mean, we have thousand years old paper and clay tablets.

I'd be less worried about the depth of the laser than the depth of the corrosion that the metal might face over time.

Glass or ceramic might work better.

laser etched ceramic is just modern clay tablets
