I'm not sure about that. For them to actually be economically useful is a high bar. More so than you think - it isn't just our brains but our strength, metabolisms, and more in a single package.
For example you need them to:
- High energy requirements in varied env's: Run all day (and maybe all night too which MAY be advantage against humans). In many environments this means much better power sources than current battery technology especially where power is not provisioned (e.g. many different sites) or where power lines are a hazard.
- For failure rates to be low. Unlike software failing fast and iterating are not usually options in the physical domain. Failure sometimes has permanent and far reaching costs (e.g. resource wastage, environmental contamination, loss of lives, etc)
- Be light weight and agile. This goes a little against No 1 because batteries are heavy. Many environments where blue collar workers go are tight, have only certain weight bearings, etc
- Handle "snowflake" situations. Even in house repair there is different standards over the years, hacks, potential age that means what is safe to do in one residence isn't in another, etc. The physical world is generally like this.
- Unlike software the iteration of different models of robots is expensive, slow, capital intensive and subject to laws of physics. The rate of change will be slower between models as a result allowing people time to adapt to their disruption. Think in terms of efficient manufacturing timelines.
- Anecdotally many trades people I know, after talking to many tech people, hate AI and would never let robots on their site to teach them how to do things. Given many owners are also workers (more small business) the alignment between worker and business owner in this regard is stronger than a typical large organisation. They don't want to destroy their own moat just because "its cool" unlike many tech people.
I can think of many many more reasons. Humans evolved precisely for physical, high dexterity work requiring hand-eye co-ordination much more so than white collar intelligence (i.e. Moravec's Paradox). I'm wondering whether I should move to a trade in all honesty at this stage despite liking my SWE career. Even if robots do take over it will be much slower allowing myself as a human to adapt at pace.
