Coding is not just the program running in memory, its also the process of distributing the mental model of understanding among the team.

If humans increasingly are kept out of coding, then who holds the mental model?

If AI holds the mental model, by definition human prompts will be over lossy channel. This is true without AI too. Software quality is directly dependent on good devs that translate from business/PM speak to technical decisions.

So is coding solved now? it was already solved decades ago.
