Future CMB and galaxy surveys are forecast to constrain the alpha-attractor quintessential inflation parameter to alpha = 2 ± 0.17 and the spectral index to n_s = 0.965 ± 0.0014.

abstract
I show that the problem of realizing inflation in theories with random potentials of a limited number of fields can be solved, and agreement with the observational data can be naturally achieved if at least one of these fields has a non-minimal kinetic term of the type used in the theory of cosmological $\alpha$-attractors.

Forecasting constraints on quintessential inflation from future generation of galaxy and CMB surveys
Future CMB and galaxy surveys are forecast to constrain the alpha-attractor quintessential inflation parameter to alpha = 2 ± 0.17 and the spectral index to n_s = 0.965 ± 0.0014.
