The key differentiator between these and "true" tech is whether the business has:
- Very high margins. If WeWork wants to grow, they need more buildings and both renting and buying require large amounts of capital. Tesla requires a significant amount of raw materials to build a car. Google on the other hand spends almost nothing to add a new customer to the database. This lets Google grow to worldwide scale with (comparatively speaking) very low capital requirements, while the others need huge upfront investments.
- A sustainable technological advantage or network effect. WeWork is "just" the Regus business model with better branding. Tesla used to have some technological advantages but the other car manufacturers are catching up rapidly. This means that in the medium term their branding will be all they have left to distinguish themselves with, and public opinion is a fickle master. Google and Meta have really entrenched themselves in their respective markets and the network effect for both is so great that I cannot see them being dethroned anytime soon.
Edit: Whoops, just read the sibling comment. Apparently it wasn't just me.
And that within those tech problems, human factors (getting people to agree, to do all the work rather than just the fun part, to deliver a sensible level of quality) dominate the problem, rather than actual tech issues.
And within THAT subset, some of those tech problems can be sidestepped by a bit of clever decision making.
