Holographic wall screens

Conference halls, office headquarters, modern art galleries and other such environments now have access to holographic wall screens. These are substantially larger versions of the holographic TV projectors which have been in use since the early 2020s. These upscale models are becoming so large that they can fill entire rooms. At this stage, they remain far too expensive for mainstream use in the home (except for luxury apartments owned by the rich and famous). However, they are a relatively common sight in workplaces, where video conferencing is playing an increasing role in business; and in entertainment venues such as movie theatres, nightclubs and stadiums.

15% of America’s GDP is based on IT now

The trend in Information Technology growth is shown below. This trend has been consistent since the 1970s and there are no signs of it slowing down. Major industries fueling this growth now include biotechnology, nanotechnology, leisure and entertainment (especially VR and related technologies) and the development of AI.

By the end of the century, over a quarter of America’s GDP may be based on IT, as the demand for physical goods and services decreases, being replaced with virtual and digital goods and services online.

Lung disease has killed 80m in China

This has resulted from the combined long term effects of (a) pollution; 20 of the 30 most polluted cities in the world are in China, (b) huge numbers of smokers; around 50% of adults, and© the widespread practice of burning wood or coal at home for cooking and heating; over 65% of the population.

China began switching to cleaner fuels, however, and has implemented a new programme of taxation, better health education, and tobacco advertising bans. This begins to reduce the proportion of deaths from lung disease from around this time onwards. Nevertheless, it continues to be a major issue for some time to come, as China makes the transition from a developing country to a developed one.
