Steinhardt, an early advocate/expounder of inflation, now has a major bone to pick with the theory. His opinion piece is more nuanced than attacking the BICEP result directly; his major point and criticism is directed at inflation. Whether BICEP has resolved B-modes or not, his main point persists. Whether he's right or not is yet another separate issue, but he has compelling points to consider. If BICEP's foreground subtraction contains an error, the situation will be resolved soon after Planck's release later this year. The already-running follow-on to BICEP2 will provide an independent check.
