Well, I would certainly agree that the brain is a very sophisticated machine, that can be "tinkered with" as you suggest, in a variety of ways with a variety of consequences.
But, the disconnect in this account is the suggestion that *therefore* "we" are our brains. Each of us has a host of cognitive capacities, some of which are computational (e.g. bodily functions). But the problem lies in explaining human mental capacities--for example thinking out of the box--that are manifestly NOT computational. If there is a single human capacity--e.g. creativity in any form--that can be shown NOT to be computational (algorithmic and deterministic), then your theory, "we are our brains" falls dead in the water. The literature is full of such questions and evidence that calls into question your thesis. One example is the so-called "frame problem" in artificial intelligence.

What is perhaps more interesting are the many cases of brain trauma and pathology that results in cognitive enhancement--rather than detriment. How is that possible? If I drop a computer on the floor, I will not expect it to perform functions that it otherwise did not perform before I dropped it. How is it that after a brain trauma, someone can become a genius in art or memory. (See Darold A. Treffert, Islands of Genius: The Bountiful Mind of the Autistic, Acquired, and Sudden Savant.)

It is not the human body that arguably needs a soul; it is the human mind. Frankly, I haven't seen any evidence that a physical computational machine, however sophisticated, can produce an independent, conscious, cognitive agent. The common assumption that "it must be the brain" because scientists cannot identify anything else than might cause it, is NOT a scientific explanation.

Cognitive psychologists have spent decades studying human cognition; and how the mind works, without being able to link mental processes, e.g. thinking, problem solving, creativity, etc. with any specified and correlated computational, algorithmic brain processes. When I look at a computer screen, everything I see can be traced to the operations of algorithmic processes in the computer's hardware and software--including all images, functions, relations, etc. Not so with the mind and brain.

True, or computers! After all, they cannot do things that cannot be explained by their physical nature and properties. Not so with human beings (and other animals) Might that not be a clue that something is missing in our understanding of human beings?
Now, maybe there is no such thing as a soul; I grant you that. But to suggest that there is no scientific reason to believe in a soul; or no evidence suggesting the existence of a soul, simply because you cannot find the soul at some location in space and time; is just ridiculous; and the product of narrow, uninformed, thinking.
