The vast majority of people using TypeScript in their projects won't run into the deeper complexity of the type system. For the average TS user the only visible impact of features like template literal types and recursive conditional types will be fewer bugs because maintainers of popular libraries used them to provide better types.
You don't have to personally understand TS's more complicated features to benefit from using TS in your project. I hope they continue adding richness to the type system so I can eliminate more bugs from my code.
Companies issue shares. These shares are listed as a liability on the company's balance sheet. Each share represents a liability to the company because it entitle its holder to a share of any dividends paid by the company.
The intrinsic value of a share is the net present value of this future stream of dividend payments, not its current market price. OP's point is that the market price of a share can be significantly above its intrinsic value in periods of irrational exuberance, such as now, creating "paper wealth" that doesn't really exist and which will evaporate when the speculators head for the exit.
