Would be interested if OP had wrote, AI built me my own blog engine. Instead of saying "I built". If person wrote 90% of code and used AI for only 10% that's only for refactoring or commenting or optimizing then it won't be wrong to say "I built". But when 90% is written by AI and user just makes minor edits its not ethical.
An on the contrary AI has itself been written by other humans and Its been trained over millions of code/work written by other humans. So essentially when AI writes some code, its those humans who were writing. If we can't credit all those humans, atleast make your statement rightfullt
