I honestly don't think Musk affected 2024 to any real extent. Look at how much narrower Harris's loss was than other incumbent losses in 2024. If anything you could make the argument Musk tanked Trump's lead like Trump tanked Poilievre.
Democrats running a candidate that lost their only attempts during a competitive primary. As well as that candidate being unable to read the room and saying they'd do the same economic decisions as the unpopular _incumbent_ Biden. And they still were within 1% of votes!
It is much easier to assume that someone else funneled money somewhere on the other side and caused your side (which is always perfect and without fault) to lose.
It is absolutely disheartening and horrible to face the reality that democracy may result in outcomes you don't like, and people may have voted wrong with full knowledge and forethought.
