         | Not at all well versed in the topic, but to me, we are at ENIAC
         | stage of quantum - those few algorithms where quantum has an
         | advantage provide a huge advantage worth a high price tag to

         | some level of viability, technical concerns aside (which are
         | not insignificant, as you point out) - but also as you
         | highlight, 'some level of viability' is not the same as
         | 'instant changes everywhere', so perceptions of hype-vs-reality
         | in the general population is a different question

           | 
           | Unfortunately, SPACs are mostly a way for those with "excess
           | wealth" (the investor class) to leech off of mom and pops
           | (retail investors).
           | 
           | The sponsors basically get interest free loans to seek out
           | acquisitions of companies that in most cases wouldn't be
           | public markets material and when they consummate a merger,
           | they can walk away with millions upon millions of dollars in
           | fees even if the SPAC performs horribly. When a SPAC performs
           | well, their profits are almost always massively
           | disproportionate to the money they invested and risk they
           | took.
           | 
           | Fortunately in this case, even if quantum computing might not
           | be all it's cracked up to be, Rigetti is a "full-stack"
           | quantum computing company, so it's an amazing opportunity. /s

               | retail investors as the bag holders in many cases. I mean
               | you could say what the pied piper of SPACS (Chamath
               | Palihapitiya) said which is "do your own due diligence"
               | but he was highly conflicted when he said that (hyping
               | SPAC deals that have since shed significant value while
               | make money on the initial transactions).
               | 
               | To be fair we still have to see how the SPACs from the
               | last year perform over the next 5 years. My guess is that
               | they went to the public markets when it was rich and
               | retail investment was high though the future is

         | IMO it is still largely in the research phase, but actual
         | quantum computers do exist. The thing to scale would be the

         | Quantum error correction is difficult though, and will take a
