David Neil Laurence Levy (born 14 March 1945) is an International Master of chess who plays for Scotland, and a businessman.

He tied for fifth place at the 1969 Praia da Rocha Zonal tournament, scoring over two-thirds and thereby obtaining the title of International Master.

[1] He played on Board One for the Scottish team at the 1972 Chess Olympiad in Skopje, Yugoslavia, scoring six wins, five draws, and seven losses (47.2%).

Levy also wrote Love and Sex with Robots, published in the United States in 2007 by HarperCollins, and in paperback in 2009 by Duckworth in the UK.

[11] Levy has also been working on a range of sexually erotic chatbots, which have been created by a team based in a lab in Malaysia.

This company was formed after a meeting with Sinclair and Paul Andrews who conceived the ZX Spectrum Vega games console.

The Vega+ console was originally intended to be delivered to backers in September 2016, but as of August 2017 the device remained unreleased amid claims of "infighting and legal battles".

[20] On 23 January 2019 a Petition to wind up the company was filed by Private Planet Limited, owned by Dr Mrsic-Flogel.

In 1968, Levy and artificial intelligence (AI) pioneer John McCarthy were at a party hosted by Donald Michie.

Prompted by the lack of conceptual progress over more than two decades, I am tempted to speculate that a computer program will not gain the title of International Master before the turn of the century and that the idea of an electronic world champion belongs only in the pages of a science fiction book.Researchers expected that a large network of computers would cooperate against Levy, until Chess 3.0, a program written by Larry Atkin, Keith Gorlen, and David Slate of Northwestern University, won the first United States Computer Chess Championship in 1970.

[27] In April 1977 he played a two-game match against Slate and Atkin's Chess 4.5, which had done well in human events, including winning the 1977 Minnesota Open,[27] and had defeated Levy in blitz conditions.

[36] Levy wrote, "I had proved that my 1968 assessment had been correct, but on the other hand my opponent in this match was very, very much stronger than I had thought possible when I started the bet.

"[38] To further stimulate the growth of computer chess, Levy suggested to Omni magazine that he would offer $1,000 to the first program to beat him if they added $4,000 to this, for a total of $5,000.

[41][42][43][44][45] In response to the suspension, Vasik Rajlich was interviewed by Rybka fan Nelson Hernandez, in which he responded to the ICGA's allegations in a statement and answered questions about the controversy and his opinions on it.

[48][49] In February 2012, ChessBase published a two-part interview with Levy in which he answered many questions about the ICGA's decision to ban Rybka.
