Grammar

Hello, I have two questions related to the grammar in the following sentences.

If you answer my questions, I thank you for answering.

(1) The basic difference between an AI robot and a normal robot is the ability of the robot and its software to make decisions, and learn and adapt to its environment based on data from its sensors. To be a bit more specific, the normal robot shows deterministic behaviors. That is, for a set of inputs, the robot will always produce the same output. For instance, if faced with the same situation, ? such as running into an obstacle, then the robot will always do the same thing, ? such as go around the obstacle to the left. An AI robot, however, can do two things the normal robot cannot: make decisions and learn from experience.

Q; In the above passage, the ? sentence was followed by –ing form (such as running), but the ? sentence was followed by the verb form(such as go). I wonder if the form ‘such as go’ is grammatically correct because the word ‘such as’ is a prepositon. And I wonder whether it is grammatically correct if it is used as going instead of go.

Also, I wonder why the word 'such as go' is correct in that sentence.

2) Most of us are suspicious of rapid cognition. We believe that the quality of the decision is directly related to the time and effort that went into making it. That’s what we tell our children: “Haste makes waste.” We believe that we are always better off gathering as much information as possible and spending as much time as possible in careful consideration.

Q: In the above passage, is ‘to gather’/‘to spend’ instead of ‘gathering’/‘spending’ grammatically correct?

Please reply.
