It depends what you mean by ‘security’. Obviously, by introducing more layers, you have more places where exploits can life. However, the biggest threat by orders of magnitude is being tricked into giving stuff up, and that risk will remain constant.

What are the chances that visiting Steven Hawking is the most interesting/fun thing you can do, if you could freely time travel? I’d much rather go look at dinosaurs, or visit the construction of the pyramids, or go listen to Martin Luther King Jr.'s speech.

Even if my goal was to meet a single scientist, I think I’d personally pick any other. Pliny the Elder, Marie Curie, Albert Einstein…

Not to be rude to Mr. Hawking (well, maybe he deserves it, I don’t know what got him in to the Epstein files…), but a thorougly average party is simply not likely to attract very many time travellers.

Kind of like how a piston in an engine also kinda just “shakes about” (because of explosions or steam or whatever) and yet delivers a lot of power.

The quality of the search depends on which app you use and how it prioritizes search results, right? I know this is a bit of a tired argument, bit since CoMaps is open-source, you could submit a patch, or at least a bug report.

I’ve encountered the same behaviour on Google Maps on occasion, too.
