It's very rare for a super billionaire like Musk to fall, of course he already had thorough financial planning before he made the acquisition of Twitter and many of his other extraordinary decisions. You know that it wasn't easy for him to get to the point he is now, he has thought of 1001 ways that we never thought of to maintain his position, and that was done not only by him, but also his financial advisors and the banks behind him. All these factors make him as strong as he is now and that is what means he won't fall, at least in the next few years, or not (?).
In business, it's normal to fail a few times with a few projects, so even if he failed with Twitter, that doesn't mean the rest of Elon's companies or his empire will collapse. The social network Twitter is facing many difficulties and we cannot deny that, but for it to collapse there is still a long way to go and we should not rush to any conclusions.
Losing business for several years is very normal for large businesses, so I see that sometimes many people are pessimistic or laugh at the difficulties that Twitter is facing, as if they have never done business before or do not have business knowledge.
People do really love on being conclusive on which they would really be making out generalization and assume out that if they fail one of their business then it would really be failing all. They arent the ones who are in his shoes on making out those kind of claims that he would really be losing it all. Just like been said that its impossible that he wont really be having some back up plans if ever there's one that would be fail.
Debt is common and even billionaires does have it and we know that having debt doesnt mean that you are already that in verge of bankruptcy. Only true investors or business minded person does really know on whats the advantage that you could really be able to get on having debts.(Long explanation).
If he ever have those debt problems then just let him be on resolving that.There's no point on trying out to elaborate about with those obvious problems. He bought twitter then its just right that he would really be
applying on the changes that he does have in mind whether it would really be that making some bad effects on the company or not. He do knows the risks and he wont be called
or achieved on being billionaire for nothing. He do knows on taking decisions and what are the risks behind it.
