When you get to the point of saying space rockets are not technology, it's time to acknowledge that somewhere in the construction of your ontology, something has gone wrong.
In this context I take "tech" to mean software, as in arbitrarily scalable with an exponential growth curve. (Not that that can last forever in software, either, but it is growth potential that drives valuations.)
Here's an even better proposal - lets try immeasurably hard to stop re-inventing words and maybe use words that people would generally understand without an accompanying definition. Where, for instance, software actually means software and tech actually means technology. :p
That's very nice, but "Tech" sometimes means an industry now, not the technology itself. Same for software. There is software the code, and Software the industry. Nobody invented a new word, but we have to understand what we're talking about in context.
