Yes, my point is that it was possible to build it before AI and in much less effort than people imagine. People in college build an interpreter in the less than couple weeks anyway and that probably has more utility.
Consider two scenarios:
1) I try to build an interpreter. I go and read some books, understand the process, build it in 2 weeks. Results: I have a toy interpreter. I understand said toy interpreter. I learnt how to do it, Learnt ideas in the field, applied my knowledge practically.
2) I try to build an interpreter. I go and ask claude to do it. It spits out something which works: Result: I have black box interpreter. I dont understand said interpreter. I didnt build any skills in building it. Took me less than an hour.
Toy interpreter is useless in both scenarios but Scenario one pay for the 2 week effort, while Scenario 2 is a vanity project.
