Why aren't we seeing real competition to twitter? Well there are 100's if not 1,000's of social media platforms, twitter is neither the best or the worst, it was effectively the first to market.

Where are all the 3rd year CS majors? Hopefully trying to innovate something useful rather than trying to break into a mature and saturated market.

"Musk can neither design nor manage". That was not the jest of your article, you conflated the two, not me. I having been involved in the Space program do know how hard rocket science is and now as a developer I do know how easy writing a "twitter" clone is.
