I'm not sure how you justify the Sony attacks but I'm sure it had something to do with corporate greed and perceived threats to free speech.
I don't see why having private keys on a server would be less secure than having these on your laptop/phone, which is much easier to steal or borrow...
My laptop is only vulnerable to theft by people I am in physical contact with and is generally my responsibly to secure while connected to the Internet. Placing SSH keys on a server means I'm giving these keys and any access they grant to the admins of said server and am placing my trust in them to keep them secure. This is fine for automated trust relationships between hosts but not generally a good idea for personal keys.
have been done by hobbyists, i humbly submit this isn't possible anymore. all of the historical advances made by hobbyists were done decades ago, involving simple concepts. all advances today are not simple, but require the support of an advanced facility, simply because all of the fundamental, simple advances in chemistry have already been scoured
I disagree. I would argue that closet chemists are not advancing chemical theory and are more likely looking at various practical applications. This simply takes a different perspective and removing ones self from corporate pressures (where something might not be seen as profitable) might provide that.
similar to hobbyist game makers of just 20, 30 years ago, and how there is no way they could compete on the same footing with modern mainline game studios and the high end graphical renderings they crank out
Yet games like Portal and Crayon Physics help change the direction of the industry.
