The tide won't lose steam if Biden wins the election. Though there will be carnage similar to the dot com bust. For one, interest rates are super low but will rise sometime soon, when the Fed raises rates at least 3-4%.
The Covid induced tech euphoria might die down and I am willing to wager that will be the case. People's habits once changed may change again, especially when the new habits have a net positive economic impact. Time saved in commuting, air travel etc. The events industry might totally boom though. So there will be some positive impact as well. Other than these specific verticals such as events and tourism, I bet the market will sour on tech innovations now more than ever.
So yeah, this is probably the right time for any tech company to go public, not just those with mediocre metrics.
