In my view, nothing materially changes. If 23andMe is a turd then an IPO through Goldman or JPMorgan isn't going to really change that, and neither will an SPAC.
Although it's a little bit "gambling" because you don't know what the SPAC acquisition will be ahead of time, I think the SPAC vehicle is great for retail investors. If you take IPOE and SoFi for example, you could have bought Social Capital Hedosophia's IPOE SPAC at $13/share or something and watched it grow once the shares were slated to be turned into SoFi shares. But in the traditional IPO process, well, you get to buy the SoFi shares at the IPO price. If you have a high net worth, that's probably fine. But if you're a retail investor - well, look at AirBnB's IPO price at $68/share and what you could actually get it at on IPO which was closer to $140 or something.
In other words, you get a little bit of exposure to the game, and of course a little bit of exposure to the risk as well which is "I don't know who they will merge with".
