Lambda the Ultimate

For those who like their PL History presented in avante guard beat poetry, a video of Steele & Gabriel's 50 in 50 speech at JAOO is made to order. Or as the link says:

A fun, artistic and enlightning presentation full of interesting facts - and who better to do it than Richard P. Gabriel and Guy L. Steele (the great Quux). Nothing more to say than the rallying cry; More cowbell!

Passing aside the Stephen Wright comic delivery of the two speakers, there are a lot of interesting thoughts, though very few are dwelled on. I think the most interesting things were the languages that they chose as expositions for the major ideas that they covered. Here's the ones that I picked out (though I ended up with only 49):
