Jobs which might disappear in 2020 in Japan

I read a really astonishing report.
The jobs which might disappear in 2020 in Japan are written.
What do you think of it?

 1 train motormen, and conductors, because most of trains will be run automatically without men.
 2 cashiers at supermarkets, because most of tags will be read automatically
3 interpreters, and shorthand writers, interpreter  because automatic speech translation system will be introduced.
4 computer programmers because programing itself will be done automatically
5 mailmen now mails are delivered by post men, but other things are delivered by other home-delivery companies so probably mailmen are absorbed by such other delivery companies.
6 newspaper carriers, paperless period will come.
7 rental video shops, download system will be introduced.
8 gas station, we won't use much gas, so gas station itself won't be run, they will be absorbed by car dealers.
9 toll men, because ETC system will be completely introduced.
10 middle traders because dealing style will change into direct dealing.
11 farmers with a side job because only big farmers will be able to survive.
12 major electronic power companies because the period of electricity deregulation will come
13 companies associated with natural energy , they won't be able to survive without subsidy.
14 Upper house members, --- I don't know, but it can't be helped.
15full-time housewives --- really? Mothers will "have to" work to earn "more " money because of financial crisis
16 Japanese board members, because Japanese companies have to be globalized.
17 middle-level executives Only skilled executives will be able to survive as an office worker.
18 clerks at company offices -- to cut labor costs
19 secretaries -- to cut labor costs
20 call center operators -- don't need to operate in Japan
21 traveling salespeople -- Internet shopping will be main measure,
22 mold craft men-- automatically
23compaines associated with printers --paperless time will be come, so such companies will be difficult to survive
24 brokers -- don't need to be in Japan
25 hedge fund managers -- don't need to be in Japan
26 financial planers-- only skilled financial planers will be survived
27life insurance sales ladies --Life insurance companies won't be able to afford these people.
28 teachers-- the number of children is decreasing, so the number of teachers is also decreasing.
