Yeah, but there's at least been some incremental progress on it:
Not to get to far off topic but I agree 100%, mmWave certainly has a place. Who knows how well it will ultimately perform but the short wave lengths make massive MIMO and beam forming/steering a reality. The next several years will be interesting.
Not sure how mmWave being blocked is surprising. 60 Ghz wifi is blocked by human hand. That does not mean there is not a place for mmWave. Cars, fixed internet, large open spaces (like stadiums, parking, or parks), or indoor das (like airports or expos).
