Surplus value cannot be extracted from technology? I guess if you mean directly.

Every technological advancement has been used to to create more value that workers produce that gets stolen by the owner class, so through the transitive property, 100% percent of the value created by technology is stolen from the people actually using the technology to produce the value.

We've had insane technology breakthroughs that have made the value we produce skyrocket, and we're in the negative, by a shit ton.

Also those data centers would be classified under "means of production" and in an actual socialistic or communistic economy would be under the control of the people and would then produce value for us.
