It’s so bizarre to read this in the present, knowing how incredible TNG was, but I get it - the original crew WAS Star Trek to them.
The dedicated fans revived this series in syndication, well after it had gone off the air in 1969, and felt attached to the characters that they had obsessed over between then and the 1980s. Like modern fans, they thought that departure from what they knew would ruin it.
I wish I could go back in time and tell them that TNG is going to rock.
It’s also funny that the article suggests that Laforge is the new Spock, and not obviously Data.
That one actually isn’t a mistake. His last name was spelled “Ryker” when they were developing the show.

If you read the initial material, Data is drastically different. There is no explicit mention of being unemotional, just that he tends to speak more formally. He’s supposed to be more like the Ilia probe than Spock.
Worf didn’t exist at first, so Geordi the teacher with bionic vision would be the most “other” character. If they’d seen any of the early press material for Phase II, Spock’s replacement there was a very junior officer.
Wow, could you imagine the show without Worf? It just wouldn’t feel right.
