Google use of AI for code migration

Original link: Google reports halving code migration time with AI help / TheRegister.

The AI did 80% of the changes itself and only 20% of the changes required human involvement.

But I will call the changes very "automation friendly":

• update from Java 8 to Java 17 [no breaking changes - just some bundling issues]
• change an id from 32 bit integer to 64 bit integer in C++ and Java code [int32_t->int64_t and int->long]
• update from JUnit3 to JUnit4 [lots of changes but very well understood changes]
• update from Joda to java.time [lots of changes but very well understood changes]
