  We construct purely non-perturbative anti-de Sitter vacua in string theory
which, on uplifting to a de Sitter (dS) one, have a decay time many orders of
magnitude smaller than those of standard constructions, such as the KKLT and
LVS scenarios. By virtue of being constructed purely from non-perturbative
terms, these vacua avoids certain obstructions plaguing other constructions of
dS in string theory. This results in a new class of phenomenological dS vacua
in string theory with novel distinctive characteristics such as having two
maxima. After examining whether these uplifted dS vacua obey the TCC, we
revisit some old problems of realization of dS space as a vacuum. We find that
not only is it phenomenologically hard to construct TCC-compatible vacua, but
also inherent temporal dependences of the degrees of freedom generically arise
in such constructions, amongst other issues. This reinforces the idea that dS,
if it exists in string theory, should be a Glauber-Sudarshan state and not a
vacuum.
