Unlikely. But first, let’s set things straight.
The bubbles that have occurred in the technology arena are the result of a sub-priming of its arbitrage (venture capital). A uniform investment thesis deployed by the omnipresent collusion of venture capital, fundamentally incompatible with detecting outliers of innovation the evolution of mankind benefits from. Save for a lucky strike.
The reason why a bubble is unlikely to happen in the space arena is that by the nature of space exploration, the risks in that segment are forcibly prime. And thus will automatically weed out the subprime investors who are known to produce a debilitating smoke-screen of false-positives and false-negatives.
