No...
Is he racking up more executive orders in his first few weeks in "the big chair" compared to predecessors? Yes.
But that's not the same as a dictator.
He's still sharing power with two other branches of government. That, alone, disqualifies him from "dictator" status.
If he were an actual dictator, his stated campaign trail agenda would've been fully implemented already.
Now, given that, breaking Executive Order records probably isn't a good look for a leader of a democratic republic, but it still doesn't make one a "dictator". Presidents have been misusing executive order for decades now, and given that the current president inherited a particularly unique situation, I'm willing to give him the benefit of the doubt for now.
If in two years from now, he's still throwing out dozens of them per week and they're not particularly aimed at addressing a bonified national crisis, then I'll start having some concerns.
IE: If in 2023, he's issuing executive orders ordering the DOE to implement critical race theory, then I'd say he's throwing EO's around willy nilly.
