  We discuss implications of the latest BICEP/Keck data release for
inflationary models, with particular emphasis on scalar fields with
non-canonical Lagrangians of the type ${\cal L} = X^\alpha - V(\phi)$. The
observational upper bound on the tensor-to-scalar ratio, $r \leq 0.036$,
implies that the whole family of monomial power law potentials $V(\phi) \sim
\phi^p$ are now ruled out in the canonical framework at $95\%$ confidence,
which includes the simplest classic inflationary potentials such as
$\frac{1}{2}m^2 \phi^2$ and $\lambda \phi^4$. Instead, current observations
strongly favour asymptotically flat plateau potentials. However, working in the
non-canonical framework, we demonstrate that monomial potentials, as well as
the Higgs potential with its Standard Model self-coupling, can easily be
accommodated by current CMB data. We find striking similarities between the
$\lbrace n_{_S}, r\rbrace$ flow lines of monomial potentials in the
non-canonical framework and the T-model $\alpha$-attractors in the canonical
framework. Significantly, $V(\phi)$ can originate from Planck scale initial
values $V(\phi) \simeq m_p^4$ in non-canonical models while in plateau-like
canonical inflation the initial value of the potential is strongly suppressed
$V_{\rm plat}(\phi) \leq 10^{-10} m_p^4$. This has bearing on the issue of
initial conditions for inflation and allows for the equipartition of the
kinetic and potential terms in non-canonical models.
