OK, its not a logical fallacy, its a false assumption.

The belief in the inevitability of progress is a bad assumption. Especially if you assume a particular technology will keep advancing.

We won't know if his assumption is false until time passes and moves future speculation into the empirical present.

A possibility is not a fact. Assuming a possibility will happen is not justified. Therefore it is false as an assumption, even if it is true it is a possiblity.

I genuinely have no idea what you're on about. One guy expressed his belief about how the future will play out, and another disagreed. Time will be the judge of it, not either of us.
