I don't think there was ever really a consensus on this. Lots of people (myself included, but also quite a few friends) always thought Bitcoin was just kinda useless. It's just that in 2012 there were comparatively low stakes (i.e. no massive energy use, not yet massive amounts of people pouring money in it, no massive amounts of "crypto snakeoil") that it just wasn't worth commenting on.
Many still believe in the idea that (certain, less well know) crypto can be used as a real currency, but unfortunately the public severely tainted it with ideas of 'being an asset'.
This comment reads as someone who is more aligned with the public's (HN) perception of modern crypto, rather than the use of it pre-2010.
Everyone thinks of bitcoin in terms of “how many USD is it?” I don’t know what the solution is but as long as we think of bitcoin as a perverted asset like housing - apparently people once again believe we will not allow housing prices to fall to any significant degree - there is no reason to use bitcoin as a currency. With so much speculation, the price is too volatile.
I don’t know what the solution is but I believe transaction costs should be minimal if not zero. I don’t know how we will achieve this but apparently there are other projects that try to get much closer to zero transaction fees. I think that is the future
Lots of us thought bitcoin was dumb back then. Lots of us still do.
