James writes: definitely some of the same elements are appearing in the Cloud Computing ecosphere that once helped build the Internet. Specifically, I see three key initiatives that have an analog in the Internet’s past:
1. The rising importance of academia. Several initiatives are out there that show the increasing importance of the academic pursuit of cloud computing on the overall effort.
2. Increasing interest in interoperability among cloud vendors. Surprisingly, vendors that stand to gain somewhat from cloud lock-in are admitting that customers are hesitant to move to the cloud for just that reason.
3. Carrier interest in new service opportunities. The Internet represented huge business growth for telephone carriers in the early 90s, resulting in changing that designation to data network carriers.

Scary stuff yet hilariously written!
Some in the 1930s, more in the war, then it just about stopped happening until the 1960s. Interesting. And more recently, of course, it became rarer because CG of all sorts became rarer.
