| Why should it? This is a new context. Though you're correct

|
| Corporate environments necessarily covers basically all of
| the economy, so I don't see the problem here.

|
| No, it only covers the corporate (ie taxable, market)
| economy, which does not encapsulate most material human
| interactions

| That makes sense, LLMs can't get creative. You have to train it

| It would be easy if only we could define what "code" and
| "execute" means. The problem is, we can't. Data is code and
| code is data. Doing things depending on data is fundamentally
| the same as executing code.

|
| We discovered technology. It has limitations. We know what the
