“Think of it as a highway, and you set aside that one lane for the carpool, right? Where, which everyone could use, but you're saying, "Okay, it's just the carpool." That's our hot box one.”

“Right? Everyone clear out of that lane except for that one experiment, and that one experiment races down the highway.”
