This is probably Isaac Asimov's "Spell My Name with an "S"".
The story concerns Marshall Zebatinsky, a Polish-American nuclear physicist. He is concerned that his career has stalled, and in desperation consults a numerologist for advice on restarting it. The numerologist advises him to change the first letter of his name to "S": Sebatinsky.

Reading the OP's description of the cover (mostly yellow, man with laser gun, flying bugs), I immediately thought of the cover below. This is the edition I have - it's currently in a box in the garage :-)
It differs from the OP's description in a couple of ways: helmet is ...
Mugwump 4 by Robert Silverberg.
The story starts:

I can't find anything about a lobster alien, but there is a weird alien shown in the intro at about 11 seconds in.
You are right, it is an Asimov story called "Someday".
The computer is called the Bard and the kids dislike it because it's not as fancy as the sweet new Visual Bard.
It ends with the Bard saying "and the little computer knew then that computers would always grow wiser and more powerful until someday...."

You have some details that are different, but I think this is the story you had in mind.
This story would be A Report to an Academy by Franz Kafka.
It was published 1917 so would fit to the theme of taking place in the 19th century. The ape narrates his story in a scientific conference (hence the title). The part of the female monkey is also in there.
The only part that does not fit is, that the ape in this story gained his intelligence not by ...
This sounds like Firefox, a 1977 novel by Craig Thomas, made into a 1982 film starring Clint Eastwood. It's about a plot to steal a Soviet fighter jet that has an experimental thought-controlled interface.
A key point in choosing the American pilot for the mission is that the interface requires the pilot to think in Russian.

You are describing Galactic Odyssey by Keith Laumer.
"Watch," Fsha-fsha said, and I followed through as he sorted them into

key-in your response patterns," he said. "Tie this one . . ." he
flipped his sorting key, " . . . to one of your learned circuits. And
this one . . ." he coded ...
