What the interview does not mention is that Scott and his wife were the centre of allegations about 6 years ago similar to those of Neil G. I don't know what the outcome was, but this may have meant that he had other things to deal with rather than write, or indeed may have been a contributory factor to his depression.
It's an interesting interview because it shows some of the spark and enthusiasm Scott had back in the 2000's, but is also more contemplative and perhaps - gasp! - more adult now than some of the stuff he was putting out there 25 years ago.
We all make mistakes, we all grow as we age. Interesting. Thanks, RM, for pointing it out.
