I found Eric Lombrozo pretty convincing in this madbitcoins episode:

But I did get the impression that it is way more political than a discussion amongst scientists and engineers. While I tend to agree with Lombrozo with his statement about if segwit2x works being a disaster for bitcoin, I can't say it puts my mind at ease. Btc going down will hurt all the other cryptocurrencies as well.
