>Time was if you wanted to get into law you’d join a firm as a clerk, learn the ropes, study for the bar, then become a lawyer....The replacement of junior staff with AI could effectively kill that route permanently.

That ship has sailed long long ago...like, 1890 long ago. There are states where you can read law and take the bar exam without a law degree (Virginia, California, Vermont, Washington), or with a partial law degree (New York and Maine), but the number of people who do that each year is minuscule compared to the number of lawyers who graduated from law school (60 to 84,000 in 2013).
