Twitter is currently profitable, and has been since sometime in 2018.

To your bigger point, I actually think nowadays we're finally seeing fewer "me too" type companies--fewer knockoff social companies (early 2010s), fewer "Uber/Airbnb for X" companies (mid-2010s), fewer hot air crypto companies (late 2010s), etc. Granted I'm seeing a proliferation of "AI" companies so that isn't to say that hype is dead, but I'm hoping we'll see something new and innovative over the next few years.
