> Where are the moon bases? Supersonic jets? Asteroid mines? Self driving cars? First three are purely hardware problems, among other things (like profitability). But asking where are the self driving cars in 2023 is a bit disingenuous. Yes, we don't have Level 5 autonomy accessible by everyone for the general public, but we already have Waymo and other cars already driving on public streets, and we do have Tesla with their FSD that some people are using for 90+% of their daily commutes. So yeah, it took longer then some people anticipated (and will still take a bit longer until these systems are widely deployed, bulletproof and affordable), but we're definitely getting there.
