I’d still take the bet. FIB and SEM stuff is highly specialized and miniaturizing it to be obtainable by a garage user seems unlikely even in the distant future. Either way, you still couldn’t take a 4090 and make it functional as a 6000 series. You’d destroy it in the process if it was even possible at all.

Nah, it's going to become democratized. It's already started.

There's been a few different stories like this lately:

People said the same thing you're saying now about computers. You're just being silly and forgetting history.

Making a hobby etching thing that isn’t anywhere close to the state of the art is cool, but not exactly anywhere close to what is needed to look at a modern chip.

You’re trivializing the challenge of modifying something that is on the order of 50nm wide and specifically designed to not be able to be tampered with.

I feel like you don't understand how time works. ;) We've barely had any of this technology 50 years. Give me 500 years and I absolutely guarantee you that I'll fuck up some 4090s with some gadget the size of a mobile phone that costs the 10 cents and it'll work perfectly fine.
