The things that major tech companies were throwing money at in 1991 were WebTV, AI, VR and PDAs.  Not - other than a few visionaries - the Internet.  Come to think of it, it wasn&#x27;t all that different from today.<p>IMHO, involvement of major corporations throwing billions at it is an anti-signal for the success of a technology.  What&#x27;ll really make AI take off is effective 80&#x2F;20 solutions combined with novel applications to fields that people consider dead.  I have no idea what those solutions or those fields are - I&#x27;d be a lot richer if I did - but I&#x27;ll predict that we won&#x27;t call them &quot;intelligence&quot; when they arise.
