Are you referring to slippery slope? That doesn't apply here since there's no small step that is causing them to believe the models will continue to get better.
What about Moore's law? Observing trends and predicting what might happen isn't a particularly new idea. You're not the only one, but I find it odd when people toss around the fallacy argument when a trend isn't pointing their way in an argument. I'm sure you use past trends to inform many of your thoughts each day.
Your points are short and without substance, so it's hard to follow along as other sibling comments seem to also indicate.
Anyway, the point stands. The fallacy is believing with certainty that something will happen because of past events. That doesn't mean prediction is futile. Might want to re-read your wikipedia pages to better understand!
