This is a follow-up to my previous post on semantics. It has been pointed out to me that this post contains several inaccuracies and grave omissions. Some of them are in the summary of Lucas’ talk, and that would probably have been noticed earlier if I had provided a link to the slides or the paper. Thanks to Lucas for sending me those by email and for walking me through the account again. I’ll briefly explain some of the misleading points later on in this post.
But the much bigger issue is that I failed to point out that Lucas wasn’t just presenting his own work. He made it very, very clear that this was joint work with Dylan Blumford (UCLA) and Robert Henderson (UArizona). I’m really upset with myself about that one, in some sense giving partial credit is even worse than giving no credit at all, and the latter is already a dick move. My sincerest apologies to Dylan and Robert.
If I had run the post past Lucas before publishing it, a lot of this could have been avoided, so I’ll make that a priority for future posts that talk about work that I’m not well-acquainted with. Alright, so let’s talk a bit what I got wrong and how that affects the central message of the previous post.
