Are you talking about the geeks at Tesla or the geeks who bought stock after the price jumped?
If the former, companies often IPO at prices below what they're worth--if the IPO is issued at a fair price, then it's Tesla that benefits, not the speculators. If the latter, buying stock because it's going up is an act of speculation, not necessarily geekishness.
