The marketing campaign for the recently-announced twelfth edition of the Merriam-Webster Collegiate Dictionary is a little… scary. While a dictionary technically can be considered a "large language model", albeit not a very interactive one, it's fair to say no one had thought of using that term to describe it before Merriam-Webster's recent fakeout ad.
The first few seconds are groan-worthy as the venerable dictionary company gears up to unveiling what at first blush appears to be a new AI, presumably to help you misspell words even more efficiently. The final reveal, when it happens, comes with a palpable wave of relief. Pitch-perfect execution here, really.
Insidious of them to almost give me a heart attack, though.
