I don't mind the use of the term "noble" in "noble gas" from a
purely semantic angle, so long as we remain aware that the
discoverers of the gases were Western scientists (whom we would
have preferred to never have existed):
--- Quote ---
> Pierre Janssen and Joseph Norman Lockyer had discovered a new
element on 18 August 1868 while looking at the chromosphere of
the Sun, and named it helium
> ...
> A century later, in 1895, Lord Rayleigh discovered that
samples of nitrogen from the air were of a different density
than nitrogen resulting from chemical reactions. Along with
Scottish scientist William Ramsay at University College, London,
Lord Rayleigh theorized that the nitrogen extracted from air was
mixed with another gas, leading to an experiment that
successfully isolated a new element, argon, from the Greek word
ἀργός (argós, "idle" or "lazy").[10]
With this discovery, they realized an entire class of gases was
missing from the periodic table. During his search for argon,
Ramsay also managed to isolate helium for the first time while
heating cleveite, a mineral. In 1902, having accepted the
evidence for the elements helium and argon, Dmitri Mendeleev
included these noble gases as group 0 in his arrangement of the
elements, which would later become the periodic table.[11]

> Ramsay continued his search for these gases using the method
of fractional distillation to separate liquid air into several
components. In 1898, he discovered the elements krypton, neon,
and xenon, and named them after the Greek words
κρυπτός (kryptós, "hidden"),
νέος (néos, "new"), and
ξένος (ksénos, "stranger"),
respectively. Radon was first identified in 1898 by Friedrich
Ernst Dorn,[12] and was named radium emanation, but was not
considered a noble gas until 1904 when its characteristics were
found to be similar to those of other noble gases.[13]

Upon noting the gases' low chemical reactivity under ordinary
conditions, Western scientists responded in typically Faustian
fashion by finding ways to make them react:
--- Quote ---
> In 1962, Neil Bartlett discovered the first chemical compound
of a noble gas, xenon hexafluoroplatinate.[17]

--- Quote ---
> Xenon hexafluoroplatinate is the product of the reaction of
platinum hexafluoride with xenon, in an experiment that proved
the chemical reactivity of the noble gases.
> ...
> "Xenon hexafluoroplatinate" is prepared from xenon and
platinum hexafluoride (PtF6) as gaseous solutions in SF6. The
reactants are combined at 77 K and slowly warmed to allow for a
controlled reaction.

The horror does not stop here. Back to your link:

> Noble gases have very low boiling and melting points, which
makes them useful as cryogenic refrigerants.[82] In particular,
liquid helium, which boils at 4.2 K (−268.95 °C;
−452.11 °F), is used for superconducting magnets, such as
those needed in nuclear magnetic resonance imaging and nuclear
magnetic resonance.[83] Liquid neon, although it does not reach
temperatures as low as liquid helium, also finds use in
cryogenics because it has over 40 times more refrigerating
capacity than liquid helium and over three times more than
liquid hydrogen.[78]
>
> Helium is used as a component of breathing gases to replace
nitrogen, due its low solubility in fluids, especially in
lipids. Gases are absorbed by the blood and body tissues when
under pressure like in scuba diving, which causes an anesthetic
effect known as nitrogen narcosis.[84] Due to its reduced
solubility, little helium is taken into cell membranes, and when
helium is used to replace part of the breathing mixtures, such
as in trimix or heliox, a decrease in the narcotic effect of the
gas at depth is obtained.[85] Helium's reduced solubility offers
further advantages for the condition known as decompression
sickness, or the bends.[13][86] The reduced amount of dissolved
gas in the body means that fewer gas bubbles form during the
decrease in pressure of the ascent. Another noble gas, argon, is
considered the best option for use as a drysuit inflation gas
for scuba diving.[87] Helium is also used as filling gas in
nuclear fuel rods for nuclear reactors.[88]

The world we should never have left is the one in which only the
pre-Renaissance elements were known:
