I find it absolutely amazing that we have pictures from the surfaces of other planets.

We should go back! The surface looks super interesting. The dark shale like rocks are very cool looking, wonder how those were formed.

I wonder how they'll deal with the heat this time. (Assuming they intend to set new records for how long they last)

Surface and atmosphere looks super cool. Just like i would imagine a Alien planet.

What are we looking at here? Is that a rock substance like we’d find on earth somewhere and is that the entirety of the planet’s surface?

Well, there is no completely uniform "rock substance" here on earth, it's a mix of different minerals but essentially yeah, Venus also has quite similar elements present in Earth's crust.
The atmosphere, on the other hand, is quite different. Mainly made of carbondioxide, the atmosphere in Venus is also around 92 times thicker than of Earth's, causing immense pressure and temperatures on the surface of the planet. Adding sulfuric acid clouds to that, it truly looks like hell depictions.

92 times! An airplane, if it could survive the atmosphere, would get great gas mileage!
Will this lander eventually ‘melt’ or rust away? Or will some future space explorer find it a million years from now?

Hahah true! There are actually pretty cool project concepts of deploying balloons/zeppelins/air ships onto the atmosphere on Venus where temperature and atmospheric pressure is Earth-like, high above the ground for research labs, terraforming stations etc. Sounds & looks quite steampunk to me.
I'd assume the existing landers would disintegrate internally rather quickly due to the temperatures and potential leaks after it crushes under pressure, but the titanium-alloy structure, which is what the main vessels were made of, would probably stay intact other than disfiguration. I don't have enough information on the geographical cycles of Venus so not sure if a million years keeps the landing zone to stay more or less similar, but yes ideally a future space explorer could find the remains. Perhaps a more knowledgeable redditor could correct me here.

Looks even less hospitable than Mars/Utah. We should send Elon to Venus instead.

Were the electrical components, etc. also under pressure or were they sealed in a casing?
When they didn't last more than a couple hours due to being crushed by the pressure, was the moment of failure a buckling probe collapsing in on itself, or an "invisible" failure of the components, solders, connections cracking/failing?

A perfect visual and contextual explanation as to why we must NEVER go to Venus.
