The media hates him, and I can understand how that can be hard to separate out from one's view of reality; but, I think whether Elon has success despite actually being terrible as some might think, or is actually really good at what he does, he's been very successful on the whole if you can be the slightest bit objective. So, given that, you would have to claim to know, really know, that it's all despite him to say he's ineffective, which is a pretty silly thing to propose unqualified.

Considering him not is pretty dumb given the success of two independent companies under his leadership (spacex and tesla). Under his leadership both companies went from nothing to successful.

You can claim that all of the success is due to the other execs at those companies, but they are still his choices following his leadership. He has the power to fire any of them so they are clearly doing what he wants.

How is it a take? Effectiveness is measured in how effective he is in achieving his goals.

He may not be a well liked or a good leader. But that is different from effectiveness.

Elon is a highly effective leader, simply because his leadership has effectively carried out its objectives. and that is a categorical truth.

Didn't he save Twitter from total bankruptcy? That's effective imo. Still SpaceX and Tesla are examples of effectiveness overall.

He may not have been effective in all his ventures but for the majority he has been effective.

I'd say going into space and creating an effective electric car product is more than optics.

Choosing great lieutenants are actions related to effective leadership.

You may consider him to be a toxic and awful person but that is independent of him being an effective leader. For example, Hitler was an effective leader.
