First, If this is correct, if alpha code succeeded, this will bring to its own demise.

I.e. as soon as it starts replacing humans, it will not have enough human generated training data, since all of programming will be done by models like himself.

Second, alphacode was specifically trained for competitive programming :

1. short programs. 2. Each program has 100's of human generated solutions.

However, commercial program are:

1. long. 2. Have no predefined answer or even correct answer. 3. Need to use/reuse a lot of legacy code.
