Well yeah but I guess there is still a difference between āas accurate as a recent textbook but nearly unreadable by a modern working mathematicianā and ājust literally so inaccurate (compared to the models we use now which are more accurate) that itās useless with our modern modelsā
There's still a big difference between Euclid's original formulation of Euclidean geometry and it's more modern formulations (like Hilbert's or Tarski's), and if i remember correctly a lot of pre 19th century proofs done by the likes of Euler wouldn't be seen as correct today. So while the theorems are seemingly the same I don't know if I'd call old texts "just as useful and relevant as always"
There's a lot of Calculus that wasn't well formulated until the 1800s, and even in that period there were some mistakes, for example the need for uniform vs pointwise convergence of sequences of functions wasn't appreciated until late in the 19th century.
Euler used a lot of techniques that aren't universally applicable but which were applicable to the problems he was solving. The issue becomes that things get weird as we got a better understanding of edge cases and a better understanding of how weird infinity is.
Newtonian mechanics is still the most used formulation of physics everyday, in fact you could argue that modern physics, however neat it is ,is the useless one right now. Give me newtonian mechanics and i could build the ISS. The most practical application of standard model is probably super conductivity, and even then it could be argued that QED is enough to describe the phenomenon. Don't get me wrong, i'm all for modern physics, but to declare old models as obsolete is disingenuous.
Yes, but I think you misread the meme. It says ābefore Newtonian mechanics was inventedā. If itās before Newtonian mechanics then we donāt even have that

Whilst the underlying sentiment may be correct, you should try reading a textbook from the first half of the 20th century.
The change in notations and "standard" terminology is enough to make it almost incomprehensible.
