You can take it a step further, LLMs can already "execute" arbitrary non-existent languages, with non-existent data. Here are a couple of examples using a tool I wrote[1]: % echo "nums 1 10 | filter even | to_words | map uppercase" | refab imagine TWO FOUR SIX EIGHT TEN % echo "with file '/tmp/top-ten-most-populous-cities.txt' do; cities = read; cities.each { |city| (city.name, city.utc_offset) }" | refab imagine Tokyo, 9 Delhi, 5.5 Shanghai, 8 São Paulo, -3 Mumbai, 5.5 Mexico City, -6 Beijing, 8 Osaka, 9 Cairo, 2 New York, -5 For what it's worth, the tool isn't specialized for this, 'imagine' is just one of many prompts it can execute. Of course the execution is non deterministic and at the moment only works for simple things, but you can imagine as LLMs get more capable and more integrated with tools this will matter less and less.
