Interesting. Somewhere among my stuff I have a first edition I bought when I was eight years old. I'm now 48, so that tells you how long this book has been around.
Gerrold's two books, The World of Star Trek and The Trouble with Tribbles, are both worth reading. He was a founding member of the Cult of Roddenberry and he bought into some of Gene's stories that we now know are false, and Gerrold hated Lost in Space, but apart from that he comes across as an okay guy.
I don't know whatever happened to my old Star Trek books, but I do recall not particularly liking The World of Star Trek. I suspect it was the first to go - I probably threw it out. In retrospect, I think David Gerrold may be sort of a forerunner of today's (generally speaking) generation of potty-mouthed, self-indulgent creators of fiction.
The whole tone of society has changed radically, and while I'm by no means a prude, just look at how young people today are influenced (among other things, of course) by this stuff. You can't find some kid on youtube who when, say, reviewing a movie, isn't spitting out mindless profanity at least every other sentence. Hardly creative, entertaining, or inspiring.
I have theories about exactly how all this started, but I won't bore you with any of that. I'll just leave it by saying that The World of Star Trek was not a treasured read from my youth.
Could not agree more, My Friend. Gerrold left a lot to be desired, and got a lot wrong. He seemed to have his own agenda, and did NOT seem to have a good Editor, but TWoST was one of the First. For that reason alone it has value. But relative and with a grain of salt.
