That list of criticisms isn't really so harsh but rather honest constructive suggestions and realistic assessments of where 3D printing is now.
That being said, there are a lot of comparisons to 70s era computers and it seems to be a valid observation. However, past performance is not indicative of future results.
In 10-20-30 years after the 70s hobby home computing club, applications are obvious.
So, maybe this is hard to ask, but what applications do you think are going to be obvious in 30 years time? What is the Visicalc of 3D printing going to be? What if there is no killer app?
