1. Jobs were you design things (code, graphics, marketing campaigns, franchise models, sales scripts, hedged trades, screenplays, new business models, retail store layouts, art, fashion etc) 2. Jobs were you follow basic instructions (flipping burgers, voice-over artists, uber drivers, sales, retail manager, factory line worker, tax accountants etc)
The first category is a subset of the current middle class, but it's much smaller.
Everyone in the second category is in for a rough ride. They will be constantly competing with machines, algorithms and millions of other people who can all follow the same manual that they have. Even jobs like sales where you'd think there has to be a human involved will be gradually eroded. Human intuition will increasingly be replaced by scoring algorithms and CRM reports. Their persistence in following up with people will be replaced by lifecycle emails, tracking algorithms and chatbots. And ever more transactions will be pushed online anyway.
I also believe that we're at the point of saturating our hierarchy of needs. Some people will try to monetise things like love, acceptance and respect of others (I can already buy a Facebook girlfriend on Fiverr). But I think this will be largely un-monetisable. Meaning we're in for mass unemployment. This is not necessarily a bad thing though, so long as we drop the stigma. People can be kept warm, dry, well fed and entertained with games and box sets, with relatively little cost.
