Pachter is pretty reliable on what has happened, as in past tense, because he has access to a lot of data.
His results are mixed on what will happen, as in future tense, because it's his opinion.
There is a big difference between the two but most aren't making that distinction.
Anyone can guess. It takes no effort to throw out lots of predictions and have some of them be correct. You are not and wiser or better for having your guesses be right. Even a blind man can hit the bullseye.
