We have 128 bit stuff in some places where it’s advantageous, but in most cases there’s not really a need. 64 bits already provides a maximum integer value of (+/-)9,223,372,036,854,775,807. Double it if you don’t need negatives and drop the sign. There’s little need in most cases for a bigger number, and cases that do either get 128 bit hardware, or can be handled by big number libraries.
He’s right though. It would be the same instructions but bigger potential numbers. Faster in some use cases, slower in others. But it would look the same.
Unless you can describe your question in a more precise and technical manner, this is similar to asking how would it feel to the touch…

The question is, how it would look like? Not whether it is practical or not
It wouldn’t “look” any different
Look isn’t meant to be taken literally. Not funny smarty pants
