"When using Java, I often change my program while it is running. recompiling classes on the fly. It works in most cases, and when it doesn't work, I believe other languages would fail as well."
I use Java fulltime at work and also have some problems where recompiling classes on the fly doesn't work. I never had the problem with Smalltalk. To assume the problems in one environment will be problems in another is exactly the problem with the original article. It assumes that because something similar exists in X, it would be the same in Y and have the same sorts of issues and rewards.
"Finally, lighttable is a proof-of-concept... It's not there yet; there are no reviews; leagues of smart engineers have tried to reproduce something similar and could not escape the POC phase at all."
A large chunk of what is in light table has existed in over a quarter century in Smalltalk environments and been used to build large and complex applications.
