Idk about engaging productivity.

If your job is just doing a lot of trivial code that just gets used once, yeah I can see it improving productivity.

If your job is more tackling the least trivial challenges and constantly needing to understand the edge cases or uncharted waters of the framework/tool/language, it’s completely useless.

This is why you get a lot of newbies loving AI and a lot of seniors saying it’s counter productive.
