Yes, regarding the question of advanced technology taking everyone's jobs, I didn't mention this in my blog as I wanted to keep it short.

Whether or not this future comes is open to debate. But it is certain that we do not live in that world today, there is still a great need for human labour currently. Yet I hear some suggestions that UBI should be implemented soon, in the next few years. We are still far from a world where machines look after our every need.

It is worth noting that previous tech advances have created more jobs than they destroy, higher level jobs that are more satisfying to people are created, lower level drudgery is taken over by machines. There has been many panics in the past about mass joblessness that would arise from technology, but it has never happened. This time may be different, or it may not be, but we should acknowledge previous concerns have always been false alarms so far.

Also, we must have an understanding of basic economics here. Taxing the machines makes no sense, as in practice it would amount to another sales tax. The companies owning the machines would have to pass on their increased costs for paying the tax to their customers, ultimately that is me and you.

For example, if a self driving taxi were taxed to pay for UBI, the cost of that tax bill would be passed on to the customers of the taxi. The ultra cheap transportation we could all enjoy would be denied. We would have expensive taxis fares, in order that we can raise the money to pay for free money for all. Again, I point to the circularity of this, why make the world more expensive to fund UBI?
