There's probably more than one variety of tea in the replicator's databanks, and of course there's more than one way to drink tea, so Picard specifies with the order.I know it doesn’t really matter. I know it sounds cool for Picard to bark: ‘Tea. Earl Grey. Hot.’
But how does that make sense? Earl Grey is a type of tea. It wouldn’t realistically refer to anything except tea, so why does Picard feel the need to specify tea? Is he afraid of getting some Earl Grey wine or an Earl Grey donut? Ridiculous.
Then there’s the ‘hot’. Earl Grey is not served cold. It’s my tea of choice, and let me tell you that not once have I been asked whether I take it hot or cold. I suppose you might get iced Earl Grey, but people usually refer to ‘iced tea’ and ‘tea’ separately. You’d be pretty miffed if you asked for a cup of tea and got some iced tea instead. You shouldn’t need to specify your tea should be hot.
And what does ‘hot’ even mean? Like if you said this to someone at Starbucks, what would that tell them that a simple order of Earl Grey wouldn’t? Tea comes hot as standard. That’s information you can’t really do anything with. It’s too vague to act on. You’d either just tell the computer ‘Earl Grey’ or give some more exact instruction than ‘hot’.
So maybe it’s some kind of Picard preference where he’s set his ‘hot’ to an exact temperature? But if it’s a preference, I’d ask again why he needs to bother saying the ‘tea’ bit. And since it’s his standard cup, surely if he was setting a preference then he’d make the wording simpler. Just saying ‘tea’ or ‘Earl Grey’ would give his default order with no need to specify temperature. This makes me think it isn’t some kind of preference he’s set.
So, Picard should really just say ‘Earl Grey’. The ‘tea’ and ‘hot’ are completely useless. I suggest we all stop watching TNG until this madness is explained or a formal apology is penned by the writers.
"Tea." He's specifying the type of beverage he wants.
"Earl Gray." He's specifying the variety of the beverage he wants.
"Hot." The only really vague command, but specific enough to tell he doesn't want it cold or room temperature.
If you're talking about ordering Earl Gray at a Starbuck's you'd have point, but a replicator is not a Cafe and it's brain is not that of barista, so it wouldn't have the common sense to know that "of course you serve Earl Gray hot," It has machine intelligence, and unless part of its function is to read people's minds, no part of Picard's order is unnecessary if he wants to get the tea he wants.
Should he have presets? Presets require identification, so whenever he wanted tea he would have to say something like "Picard, beverage choice one-A" or "This is Captain Picard. Replicate tea according to standard parameters" or the replicator would have to have biometric technology in order to determine it's Picard ordering the tea and some schmuck from the lower decks. How is any of that more efficient than just speaking four one-syllable words into the machine to get the same result?
I hope you're joking about the boycott/apology thing, because it would be the height of idiocy if you were serious.
