I cannot imagine this to be true, cause imo current LLM's coding abilities are very limited. It definitely makes me more productive to use it as a tool, but I use it mainly for boilerplate and short examples (where I had to read some library documentation before).
Whenever the problem requires thinking, it horribly fails because it cannot reason (yet). So unless this is also true for google devs, I cannot see that 25% number.
