Is it a 100% fact that this is a complete different thing than the refurbishment of the Falcon 9, or is that just whishful thinking or what SpaceX claims? Don't get me wrong, this is an absolute fascinating engineering Marvel, and I am not a SpaceX hater. But Elon often made wild claims, and many fans just blindly applaud it and take it as if it was already reality ("passenger Earth to earth transport" with starship as an alternative to airplanes is still a stupid idea that will never happen, sorry). The breakthrough idea is not "building the strongest rocket ever made" or "catching huge rocket boosters". Instead the vision was: Space flights become as common as airplanes, because you basically only have to pay for the fuel. And we still have to wait if that actually will work out.
Don't forget: Already with the Space Shuttle back then they claimed that flights will become cheap and can happen often. But that didn't work out, because the refurbishmend of the Orbiter needed much more money and time than expected. And does SpaceX have the ultimate idea for the Starship (so the upper stage, that goes into orbit) concerning their heat tiles etc, so that it can be get ready for the next flight quick and cheap? Yes, Starship will land. Yes, we will see the first full flight of of an entire Starship and everybody will applaud. But that alone is not what was promised. That alone will not change the world.
I read a german article about ITF5 . He often write about space stuff, it was not an "anti" article, but just quite neutral about the goals that were achieved and the challenges that are still there. One interesting point was, that SpaceX had to put more heat protection on the upper stage that was heavy, and that the fuel that is needed for the landing is more than expected. So that this particular flight did not have much payload capacity. Oh, and an important part of the idea was the refueling in orbit. I have heard that is already necessary not only for Mars, but already for the moon? And even for that it needs several refuels? Besides computer graphics we haven't seen anything about refueling, it is just an idea.
However, I observe it, it is fascinating, but I will wait what actually will happen and what promises really will be fullfilled. And I don't join the "This changes everything!!!" choir too early.

@JesusistheonetrueGod So funny, how strong religious people argue against the big bang. Actually the big bang theory was mainly made popular by an astronomer, who was also a theologist and priest. Back then some other scientists critized the theory, called in "pseudoscience" and said, that it was made by people, who were not neutral scientists, but instead were searching for a theory that is compatible with a belief in God who created everything. The Big bang theory basicly says, that space and time has a beginning. The big bang describes the moment of creation. The other theory, that was favoured by the criticial scientists, is, that the universe was always there, and that there was no creation.

They will use heatshields, and to me, that is still the biggest challenge. I mean, this flight was epic, and it is amazing what they achieved. But the biggest question mark to me is still the full reusing of a spacrcaft after ree-ntry. The Space Shuttel already was a vehicle that came back from orbit, landed on the ground, and was made to be "reused" and so flights should be cheap and should happen often. But the reality was: It was more like "refurshibable" but not "reusable". So it took much more time and money than planned, to make it fit again for the next flight.
I totally believe that Space X can make a starship that comes down and land as they plan it and as they show in the simulations. But the question is: What will be the conditon of that thing after re-entry from orbit, and how easy can it be used again? Elons idea is: With a fully reusable spacecraft the(more or less) only costs for a launch will be the fuel. Like it is the case for airplanes, and only because of that flights are affordable to everyone. We will see, if he can realize that...
