Boo, this is unnecessarily negative. Here's some cool things that are happening in entrepreneurial space.
First, SpaceX is using its reusable launch capacity combined with the StarLink constellation to dramatically lower launch costs over the next decade. Here's a nice writeup on why StarLink is important (https://caseyhandmer.wordpress.com/2019/11/02/starlink-is-a-...). SpaceX is essentially using StarLink to 'soak up' all the extra, cheap launch capacity it will produce (demand generation) until the rest of the industry wakes up to this new reality. This will help SpaceX both produce fantastic profits to fund capital investments for space endeavors while also increasing the heavy launch capacity possible to space, vastly increasing commercial opportunities in the 2020s.
Another healthy space area has been nanosats and cubesats. Nanoracks (http://nanoracks.com/) has created a healthy business out of the ISS launching these, while Planet Labs (https://www.planet.com/) has created a near-earth observation constellation that is commercially doing well using these kinds of platforms. Small launch providers for nanosats and cubesats, as well as a healthy diverse ecosystem of hardware suppliers (https://blog.bliley.com/top-20-best-cubesat-satellite-manufa...), has made this an accessible area of space.
Space-based manufacturing has indeed been slower to launch. The Space Shuttle did pioneering work in showing that fiber-optic cables based on something called ZBLAN could be produced in orbit (https://upward.issnationallab.org/the-race-to-manufacture-zb...), and they are an ideal space-based manufacturing product: they are straightforward to produce in orbit, can fetch a very large price, and have a very small downmass back to earth. Made in Space has done recent pioneering work demonstrating producing ZBLAN in space (https://madeinspace.us/capabilities-and-technology/fiber-opt...). Here's a great list of other startup companies pushing forward with space based manufacturing: https://www.factoriesinspace.com/manufacturing-companies
One of the most exciting developments is Made in Space's Archinaut project (https://madeinspace.us/capabilities-and-technology/archinaut...), which promises IMHO to allow us to build complex structures in space from small-fairing rockets. Significantly, NASA recently gave a large grant to Made in Space for an Archinaut demonstrator mission in the near future (https://www.engineering.com/AdvancedManufacturing/ArticleID/...).
Not to be crass, but the last thing we need are cynical old economy space folks who have given up on moving space forward. There is a diverse, vibrant space economy under the surface if you know where to look; it's not Apollo or O'Neill cylinders (https://en.wikipedia.org/wiki/O%27Neill_cylinder) in space but real companies that make real profit and move humanity forward have been quietly working behind the scenes the last two decades. Much of this is due to low-cost launch, more accessible satellite platforms like cube and nano-sats, and a NASA that is more inclined to be a market-enabler for space with programs like COTS (https://www.nasa.gov/commercial-orbital-transportation-servi...), CCDEV (https://en.wikipedia.org/wiki/Commercial_Crew_Development), and more. Rome wasn't built in a day.
