I haven’t written a novel - but written lots of poetry. Nearly got published in Israel in my late teens, but lacked the funds to supplement the initial ‘investment’. Which I guess is a non-anecdote really!
My other half, on the other hand, had written a novel - 90,000 words, whilst he was travelling in South America in the late 90’s. He used to have a serious objection to all things Artificial Intelligence, and this was planned as his meticulous argument against AI, in the form of a novel. He was young(ish) and rather pompous in his ambitious, but no one would publish him. He never allowed me to see it, let alone read it - he now feels deeply embarrassed about the whole thing… so another non-anecdote really.
Strangely enough, my ex-husband did his MSc on Artificial Intelligence, so I had a husband for each opinion!
