What are the chances that visiting Steven Hawking is the most interesting/fun thing you can do, if you could freely time travel?

Not only that, apparently the machine he used to speak was rather difficult to use quickly, and drafting responses could take hours or days depending on how much needed said. Pretty much all of his appearances after he was unable to use his voice were heavily scripted ahead of time.

So unless you’re visiting Steven Hawking when he still could talk, it’d be pretty boring as you couldn’t have a proper back-and-forth conversation
